Fashion news: Kylie's lingerie, Paris' beefy look!

Welcome to the weekly fashion round-up, where we bring you the latest on supermodels, style, designers and everything in-between!

Which supermodel came clean about her addictions this week? Which reality TV star is set to expose some more skin in a commercial?

Here's the lowdown on the latest fashion news!

The secret to Kylie's sexy looks -- great underwear!

Pop diva Kylie Minogue has credited the secret of her sexiness to good underwear and all-over body makeup.

"I know a lot of tricks to make everything look good, basically very good underwear and all-over body makeup. That's my secret," she told the Daily Mail in an exclusive interview.

The 42-year-old also complained that her bottom often gets more attention than she does, but said she has no plans to stop wearing hot pants.

"My face has been outshone by my bottom. After the Spinning Around video, people became a lot more interested in my behind than they were in me. It makes me laugh, and every time I pull on a pair of hot pants I think to myself, 'This is the last time', but it never is. I haven't quite put an end date on hot pants yet," said Minogue.

She said being thought of as sexy made her happy.

"I've never had a problem with being a sex symbol. I'm a woman and it's a lovely compliment. It's a nice feeling that people like how you look. I've always been very comfortable with it," she said.

Minogue said she still couldn't believe she is 42 now.

"Part of me feels like I'm still 21 and I always will be. A lot of people thought I would have a problem when it came to turning 40, but I didn't -- I totally embraced my forties," she said.

"When I'm in the retirement home, I'll still be getting out my old costumes and feathers and putting on a show. It's what I've been doing my entire life and it's a total blast," she added.

And there is another side to Minogue that most people have not seen.

"I can be a total nerd. I love to pull on casual clothes and play golf, and when I'm with my nephews, I turn into this woman who rolls around on the floor, changing nappies and getting covered in poop," she said.

It certainly seems like pop divas are getting sexier as they get older. Jennifer Lopez has added another feather to her cap -- she has been named the first ever Global Ambassador for shaving brand Gilette.

Lopez and her famously fabulous legs will star in the new campaign for Venus Goddess, dedicated to encouraging women to feel their most confident, powerful and beautiful -- inside and out.

"The Venus brand empowers women and speaks to the 'goddess' in every one of us," Stuff.co.nz quoted her as saying.

The newly established Venus Goddess Fund for Education will enable global educational opportunities for women through partnership with organisations such as CARE International, the Step Up Women's Network and Lopez's own Maribel Foundation.

Lopez has also recorded a remake of the classic Venus song as part of the campaign.

"Music is one of my great passions, so being able to record and perform a remake of the iconic Venus song was a really special part of this campaign. I love that I could express my own passion and creativity, and hopefully inspire other women to do the same...whatever it is they love doing," she said.

"Every woman is a goddess in her own right when we let our best feminine self shine through. Venus keeps my legs looking beautiful, giving me the confidence to feel just like a goddess," she added.

Celebs and their enviable assets! It seems that more and more Brit women are opting to go under the knife to get Mad Men star Christina Hendricks' 'hourglass figure'.

Last year there was a 10 per cent surge in the number of women having breast enhancements in the UK to 9,418.

Plastic surgeons say it is because women want to look like Mad Men star Christina Hendricks, reports the Daily Mail.

"The Christina Hendricks effect is significant. She looks stunning and lots of women aspire to a figure like hers. No one believes any more you have to be stick thin to be beautiful," a surgeon said.

Even Liberal Democrats Equalities Minister Lynne Featherstone said the 35-year-old's size 14 figure is one all women should look to -- rather than thin models with "unattainable bodies."

"Christina Hendricks is absolutely fabulous. We need more of these role models," she said.

Figures to be released by the British Association of Aesthetic Plastic Surgeons (BAAPS) reveal that overall, the number of people undergoing plastic surgery rose five per cent to 38,274.

Of all the cosmetic procedures carried out last year, 90 per cent of them were performed on women.

Hendricks' Mad Men co-star January Jones is also basking in adulation lately -- Italian fashion designer Donatella Versace has been heaping praise on her.

In a behind-the-scenes video of her recent ad campaign, the woman behind the Italian luxury brand said she chose the 33-year-old spokesmodel to be the face of Versace accessories because "she looks like the most glamorous actress of our time."

Jones appears nude in the ads for Versace accessories, save for high-heeled shoes and a strategically placed handbag.

"She's a girl who has no fear," the New York Daily News quoted the designer as saying.

And speaking of high-end fashion -- Hollywood actress Keira Knightley might have tens of millions of pounds piled up in the bank, but only splurges on designerwear if her mum says it's okay.

The Pirates of the Caribbean star reveals how she only bought the most expensive item in her wardrobe -- a 2,795 pound sheepskin coat from Burberry -- after getting the green light from her mother.

"My mum was like, 'You cannot spend that amount of money on a coat', and I was like 'No, you're right I can't, I can't'," the Telegraph quoted her as saying in the March issue of Elle.

"And then literally it was months, months of thinking about it and thinking 'I'm not going to do it, I'm not going to do it.' But then she said 'Right, if you're going to buy it, you have to wear it all the time'."

"I wore it everyday last year and I'm going to wear it every day this year," the actress said.

She also admits that she's not the most inspired everyday dresser.

"I'm just not very good at thinking about what to wear first thing in the morning. I just think, 'It's cold, I want a jumper on'," she added.

Harried new mothers trying desperately to regain their pre-baby bods may want to take a swipe at her for it, but Australian supermodel Miranda Kerr has revealed that she didn't get any stretch marks during her pregnancy.

The 27-year-old said she managed to have her whopping baby Flynn without getting any stretch marks.

"As you know, I had a huge belly and was convinced I would have stretch marks as a result," the Daily Telegraph quoted her as saying on her blog.

The Gunnedah girl put her good fortune down to twice-daily body brushing and using plenty of her moisturiser.

In more supermodel news, cancer experts have criticised Gisele Bundchen for describing sun lotion as 'poison'.

Despite having previously starred in an advertising campaign for a range of sun creams, Bundchen said she does not use the products herself.

"I cannot put this poison on my skin," she said, referring to the widespread use of chemicals in lotions to absorb UVA and UVB light.

Dr Dolival Lobao, head of dermatology at Brazil's National Cancer Institute, condemned her comments.

"Sunscreen prevents damage to the skin and is of fundamental importance for the prevention of cancer," the Telegraph quoted Lobao as saying.

"This is not any poison. When a public person makes a statement like this, it creates confusion and I find that regrettable," Lobao added.

Jessica Harris, senior health information officer at Cancer Research UK, said: "Using sunscreen with at least SPF15 can help to protect your skin, along with spending some time in the shade and covering up with clothing."

"Sunscreens are fully tested before they can be sold and are not harmful to the skin," Harris added.

On the subject of skin, reality TV star Kim Kardashian is all set to bare hers in a new ad for Skechers during the Super Bowl.

The reality starlet will be showing lots of skin in a steamy ad for Skechers after the two-minute warning in the fourth quarter, reports AdAge.

The brand is betting millions that Kardashian can get younger people into their shoes.

"Kim will be challenging people to get rid of your bad habits and get your friends on board," the New York Daily News quoted Leonard Armato, president of Skechers Fitness Group, as saying.

If Kim's making headlines, arch rival and fellow reality star Paris Hilton is never far behind -- she revealed an impressively pumped-up physique at Sao Paulo Fashion Week.

The socialite and hotel heiress, known for her slender figure and Barbie doll looks, walked down a catwalk in Brazil this week, reports the Mirror.

It looks like she's made a huge change in her gym routine to transform her body.

"Paris seems to have undergone a dramatic image change," the Mirror quoted one onlooker as saying.

Paris, who has her own line of fragrances, makeup and clothing, seemed to relish her new look as she strutted her stuff for Brazilian fashion brand Triton.

Also in Sao Paulo this week were Demi Moore and Tallulah, who don't look like mum and daughter but like sisters -- both ladies showed plenty of spray-tanned leg and slim figures at a recent fashion show.

The Hollywood actress, 48, herself looked runway-ready, as she arrived with husband Ashton Kutcher for the Colcci show at the Sao Paulo Fashion Week in Brazil, reports the Daily Mail.

Kutcher was starring in the fashion show, previewing the label's 2011-2012 fall collection. At the end of the show he emerged alongside the designer, who hugged him to thank him for his hard work.

Earlier this weekend, the couple attended a party hosted by Brazilian football star Ronaldo to kick of Sao Paulo Fashion Week.

The dinner party, held at Dom restaurant, was attended by a host of local celebrities as well as the Hollywood superstar couple.

Here's someone who should have showed a little less of her figure in Sao Paolo! Christina Aguilera is not shy of revealing her curves and this time she really grabbed the spotlight.

All eyes were on the pop star, who flaunted her assets at a press conference in Brazil on Tuesday, with her ill-fitted dress struggling to grasp her impressive cleavage, reports the Daily Mail.

Aguilera was also in Sao Paolo to attend the fashion week and launch her own clothing line.

She has followed in the footsteps of Beyonce, Nicole Scherzinger and Fergie by designing a line of clothing for Brazilian department store C'n'A.

The 29-year-old singer was sporting her trademark heavy make-up and red lips for the press conference and wearing a low-cut black mini dress.

Online rumours have suggested that the star had to postpone the shoot after she gained a little too much weight in recent months and couldn't fit into the clothes.

Speculation has been rife for years that the Dirrty singer had gotten a breast enlargement, and in December shots of a large scar under her arm led to suggestions that her secret was out.

Looking to hop onto the celeb fashionista bandwagon along with Christina Aguilera we have Katie Price, aka Jordan, who recently split from hubby Alex Reid.

The former glamour model will debut her new budget-price collection next month and her range will include handbags, sunglasses and posh frocks.

She is teaming up with London designer Lamis Khamis for the new range, which is called Day 22 and will be an affordable set of clothes and accessories for men and women.

"Kate really wants this new fashion range to be a huge success," the Daily Star quoted a source close to her as saying.

At the other end of the spectrum we have The King's Speech star Carter, who has admitted that she's made a few fashion mistakes on the red carpet, but insists that fashion is all about having fun and mismatching.

"Sometimes I get it right and I sometimes I get it wrong," People Magazine quoted the actress as saying.

"But fashion is all about having fun. I think fashion has been hijacked by the fashion industry creating rules on what one should wear and I feel like breaking the mold and seeing that the world won't crumble.".

The Oscar nominee raised a few eyebrows by attending the Golden Globe Awards this year wearing one red and one green shoe.

"Why not wear mismatching shoes? Who says we can't? I was just having fun," she said.

She also admitted that she wears corsets to make her chest look bigger. Speaking on the red carpet, Carter revealed what she was wearing.

"Today I'm wearing huge breasts. No, it's a corset. They're still real -- if you get a proper corset," the Daily Mail quoted her as saying.

She said it fooled people into thinking her breasts are bigger than they are.

"It's amazing what a corset will do," Carter told US Weekly. "I'm not all that well-endowed. These are my Golden Globes. Who needs Golden Globes when you've got these?" she added.

"For me, fashion is all about fantasy and putting unlikely things together. That's what I love. I genuinely love dressing up."

Carter praises Lady Gaga for her daring fashion choices.

"I love the way she dresses. She's like a work of art," she said.

"Anybody who is inventive, different or has fun like her, I love and admire. I'm amazed that she's able to stand up in some of those shoes she wears."

"I feel honoured to be compared to her but I would probably be called Lady Haha. She's fantastic," Carter replied about what it's like to be compared to the Bad Romance singer.

These days, celebrities are taking fashion to a whole new level. And newlywed Katy Perry is just one of them.

The singer has become the latest celebrity to sport the rather scary stiletto nail trend.

The California Dreams singer posted a photo on her Twitter page showing her latest manicure -- long, gold and very pointed.

"Nails for the Day...This took 4ever to type," Stuff.co.nz quoted her as tweeting.

Other celebs to have tried out the rather impractical trend recently include Lady Gaga, Fergie and Rihanna.

Supermodel Lara Stone has revived Marilyn Monroe's most famous pose for a Comic Relief advertising campaign.

The 5'10", size eight catwalk star underwent an extraordinary transformation to become a look-alike for the Hollywood style siren.

With her bouffant hair and pleated white dress she does her best impression of the actress in the classic 1955 film The Seven Year Itch.

It contains one of the most iconic images of the 20th century -- Monroe standing on a subway grate as her dress is blown above her knees by a passing train.

"I had so much fun being Marilyn Monroe for the day and recreating such an iconic shot," the Daily Mail quoted Stone as saying.

"It was an honour to be asked to take part in such an important campaign. Red Nose Day is such a simple way for everyone to get involved and raise money to help the people that need it most in the UK and Africa," the model said.

She is joined by a host of famous names to launch this year's Red Nose Day campaign, including her husband David Walliams, John Cleese, Alesha Dixon, Amanda Holden, David Tennant and Alexandra Burke.

They're encouraging people to do something funny to raise money for Comic Relief on Red Nose Day -- or at the very least buy one of the noses or Vivienne Westwood-designed tee-shirts, which both raise funds for the cause.

Speaking of hot ad campaigns, former Hills star Audrina Patridge showed off her sexy bikini bod in a new one for Bongo.

This is her second year of partnership with the brand, the spring 2011 line of which has the star flaunting her bikini body in a black two-piece and modelling a variety of tank tops and shorts.

"I am thrilled for my second season as the Bongo girl!" the New York Daily News quoted her as saying.

"It has been a wonderful partnership and I really love the product. I wear the jeans and tops constantly and can't wait for spring to wear the bikinis on the beach and all of the new dresses, shorts and sandals."

Rihanna has never been shy of revealing her sexy self, but her new and already controversial SnM music video seems to have pushed all boundaries.

This latest number features the singer in a series of latex outfits engaging in SnM pursuits, reports the Daily Mail.

Throughout the video, Rihanna is seen poking fun at the media, with the plot set in a mock press conference.

The video, shot by Melina Matsoukas -- who also directed her track Rude Boy -- opens with the 22-year-old dressed in newsprint, being dragged into a room full of journalists.

She gives an interview from behind a plastic sheet as the reporters scribble away while wearing ball mouth gags.

Soon they are bound by latex tape and lying on mattresses as Rihanna, now wearing latex underwear, writhes around on top of them and whips them as they squirm.

Even gossip blogger Perez Hilton is said to have made an appearance, apparently being led on a leash by the singer, who treats him as a pet while whipping him outside a suburban house.

Ever felt embarrassed after realising that your white or black bra was showing through your top during that important party? It could now become a thing of the past.

British retail giant Mark and Spencer have launched a range of 'Nearly Naked' lingerie that blends perfectly with any woman's skin and appears invisible under clothes, reports the Daily Mail.

While other attempts at making 'nude' underwear have tended to take a one-colour-fits-all approach, the 18-pound 'invisible' bra comes in four shades to match a range of skin tones.

Using a spectrophotometer, a machine that can assess the individual shades, which make up the final colour, the company scanned the skin tones of more than 1,000 customers.

The results were then compared with ethnicity data from the Office for National Statistics to select colours that were an exact match for human skin.

The bra is available in sizes 32A to 40D. The range also includes matching briefs for 8 pounds.

"Women are recognising the need to wear a neutral-coloured bra which complements their own skin tone and can create a 'disappearing act' under clothes," said Soozie Jenkinson, head of lingerie design for M and S.
