Arab magazine breaks taboo by featuring first ever model in bikini on cover

An Arab magazine based in Israel has broken taboos by being the first to feature a bikini-clad model on its cover.

Yara Mashour, who is an Arab Israeli and editor-in-chief of the magazine Lilac, has set out to challenge customs and tradition and her latest milestone is perhaps her biggest triumph to date.

The model, Huda Naccache, 22, from Haifa, is pictured posing in a black sequinned bikini on the cover, and her fixed stare portrays the magazine's determination to make a difference.

In a region that is known for gender discrimination, women's rights violations and spousal domination, Lilac is daring to tread where no other publisher in the Middle East has ventured.

"Since I established Lilac in Nazareth, Israel 10 years ago, I set out to break taboos regarding women in society...I worked on empowering and liberating women," the Daily Mail quoted Mashour as saying.

"Huda is the first Arab model to appear on the cover of an Arabic magazine in a bikini. Lilac is the first Arabic magazine to show a cover with a bikini!"

"I don't recall this being done elsewhere in the Arab world. I have been working for a decade on changing society so Arab women can have more rights and freedom in the Middle East," she stated.

As for Naccache, she says she is honoured to be part of the gradual -- and often stymied -- move for change in the region.

"I am very proud to be the first to wear a bikini on Lilac's cover. I am a professional model and this should be normal," she stated.

"At the beginning, I was reluctant to appear on the cover in a bikini, because of concern for our society's norms."

"Later I realised that if I want to be successful, I can't choose what I want, and I talked to my parents, who became convinced by my view. I would never do something without their blessing," she added.

Kelly Brook has bared it all for the new 'Whose Skin Are You In?' PETA campaign, as she posed for a photoshoot flaunting her snake-painted body.

However, at the launch of the photo, captured in Bryan Adams' Chelsea studio, Brook maintained her modesty by covering up her curves to perfection in a pretty tiered dress which she paired with black strappy heels.

The 31-year-old model-actress ventured into the campaign to voice her protest against how snakes, lizards, alligators and other exotic animals are killed for uncouth human needs.

"It makes my skin crawl to think about the violent ways snakes, lizards, alligators and other exotic creatures are raised and killed for boots, bags and belts," the Daily Mail quoted her as saying.

"Our message is to support the designers who are creative without being destructive, and go for the great fakes that pay tribute to the animals' beauty without killing them," she added.

Pamela Anderson has written a letter to European Union (EU) officials, requesting them to implement a plan to outlaw cosmetics that have been tested on animals within the next two years.

The Baywatch star, who is an avid animal rights activist, is urging European Commissioner for Health and Consumer Policy John Dalli to honour the deadline, which was put in place for a blanket ban on sales of products developed using the controversial procedure by 2013.

Anderson wrote the letter on behalf of People for the Ethical Treatment of Animals (PETA), following rumours officials are planning to delay the legislation.

"I was distressed to hear from PETA that the European Commission is considering delaying the 2013 deadline to end the sale of cosmetics tested on animals," Contactmusic quoted her as writing.

"I hope it's just a nasty rumour, but if there's any truth to it, please do right by the European citizens who overwhelmingly support the ban -- as well as the thousands of animals affected -- by honouring the original deadline."

"I love cosmetics, but there's no reason for animals to suffer for lip gloss and eye-liner; those cruel tests are from another era. "

"Today, there are effective and 100 per cent humane non-animal testing methods."

"We also already know thousands of ingredients that have a long history of safe use. Hundreds of manufacturers have already been using them for years! Please, don't turn back the clock."

"This legislation is a huge step forward and sets an example for countries around the world to eliminate animal testing for cosmetics. Please ensure that the ban moves forward without delay," she stated.

Madonna's daughter Lourdes Leon was pictured promoting her mother's fashion label Material Girl at a special show in New York this week.

Lourdes, 14, looked like a vintage movie starlet with bright red lips, a yellow heart-print dress and tumbling dark hair.

It was the label's first anniversary celebration at a Macy's department store, which included a runway show and a brief appearance by Madonna herself.

However, she seemed more than happy to take a back seat and look on with pride as Lourdes explained the hottest looks from the range.

"When it comes to clothes for warmer weather, it's shorts for spring that are all the rage for the girls. I'm, like, obsessed with them," the Daily Express quoted Lourdes as telling the crowd.

Later, she cut a four-tiered birthday cake covered in black and pink icing and decorated with sparklers.

Material Girl is aimed at teenagers and young women who want to emulate the high-end fashion they see in magazines without shelling out hefty sums from their pockets.

Naomi Campbell was pictured suffering a wardrobe malfunction at the Toni&Guy hair fashion show, when her tuxedo jumpsuit failed to cover her modesty.

The 41-year-old model had an embarrassing moment, leaving her nipples on show while climbing back into her car to head home after the event at Somerset House, the Daily Mail reported.

Campbell wore a black tuxedo sleeveless jumpsuit with satin lapels by Alexender Mc Queen, with Christian Louboutin heels for the evening.

She arrived over half an hour before the event started and had styled her hair in ringlet curls with a straight fringe for the event.

Harry Potter star Emma Watson has revealed that she would rather look natural instead of piling on cosmetics, as she thinks beauty comes from within.

The 21-year-old beauty admitted that her biggest beauty faux-pas is wearing too much makeup.

"The funny thing about me is that I do have a lot of products -- I've always loved makeup and its ability to transform you," Contactmusic quoted her as telling Hello! Magazine.

"But I don't actually wear a lot of it, so there is an irony that I own so much of it but wear so little. But I do love beauty products."

"But wearing too much makeup has been my biggest beauty faux-pas. I truly, truly believe that beauty is something that comes from within. You can only really look beautiful if you feel beautiful on the inside," she added.

Tamara Ecclestone has stripped yet again for UK-based lingerie brand Ultimo.

The 27-year-old socialite opted for the racy look while modelling for the new lingerie range, the Mirror reported.

The elder daughter of F1 supremo Bernie Ecclestone paired a blue satin two-piece with stockings for one of the photographs and wore a pretty purple slip from the latest collection for another from the photoshoot.

Pregnant Beyonce Knowles and her mother recently strolled hand-in-hand on the catwalk at the London Fashion Week, as the singer launched the latest collection from her fashion label House of Dereon.

The mother-daughter duo looked pretty swank as they dressed in shimmering black for the launch.

Beyonce was thrilled about the event as it was her first fashion show outside the US, the Mirror reported. The 30-year-old also couldn't stop gushing about her mom and how she used to make clothes for her band Destiny's Child.

"It's not like this strange battle between mother and daughter, like people expect. My mother's been designing for Destiny's Child and myself since we first started out," the Mirror quoted the singer as saying.

"Dereon is my grandmother's name and it comes from three generations of style. My grandmother used to sew beautiful garments for my mother -- and she did the same for me," she added.

The show attracted a star-studded guest list, including Paloma Faith, Nicola Roberts, Kate Moss and Twilight star Kristen Stewart.

Twilight actress Kristen Stewart was voted the sixth sexiest woman in 2010, but admits that she is very bad when it comes to style and gets very confused when she has to decide what to wear.

Stewart, 21, said that she goes through various phases deciding what to wear, but "loves" the decision-making part.

"All over the place right now. I have different versions of myself and a standard uniform -- I wear jeans. It's cool to have another side of things. I have phases," Contactmusic quoted her as telling vogue.co.uk when asked to describe her personal style.

"I love what I wear, I mean I love choosing what I wear," she added.

Though Stewart says that Fashion Week isn't usually her scene, she revealed that she is still very "interested" in fashion.

"Actors and actresses have a hand in both worlds (acting and fashion). You have to stay involved in it to be interested," she said.

Mariah Carey's husband Nick Cannon has revealed that the singer is working very hard to get her pre-baby body back.

The 30-year-old actor also said that Carey, 41, is focused right now on every aspect and that the We Belong Together hitmaker is going to come back and knock out the world.

"At two months she was walking around in a bathing suit," Us Magazine quoted him as saying.

"Every day she's just killing it. I personally think she's going to come out looking better -- looking like it's 1990! I think that's what she's aiming for, and I think she'll reach that goal."

"Obviously she pays attention to her diet and eating properly."

"She does long, long hours on the treadmill. It's all doing it the right way," he added.

Pop icon Lady Gaga has been crowned the queen of the celebrity catwalk, beating Kate Moss and newlywed royal Catherine.

The Poker Face singer topped the poll, conducted by clothing brand Hot Tuna, for her bizarre range of stage outfits.

Moss came second and the Duchess of Cambridge was placed third.

While Kim Kardashian and Gwyneth Paltrow rounded up the fourth and fifth place, Victoria Beckham was placed last, behind Rihanna and model/actress Kelly Brook, the Daily Star reported.  

Prince Harry topped the men's poll, with David Beckham and Kasabian rocker Serge Pizzorno in second and third place.
