IMAGES: The top 20 sexiest models 2011!

Here's a list of the hottest catwalkers for the year 2011, according to a survey by fashion website Models.com

They've made their fortunes and scaled the rungs of fame with their drop-dead gorgeous looks.

And each year, as the competition gets stiffer, the top catwalk queens of the world jostle each other for the prime spot on this list.

Compiled by Models.com, the list of the 'Top 20 Sexiest Models 2011' is based on each candidate's visibility, market impact and client list, which means that there is a chance that two beauties sometimes end up sharing the same position.

And the list for this year is as follows!

19. Alyssa Miller

This 20-year-old American bombshell made a splash in fashion at the age of 15. She has landed the covers of such prestigious glamour magazines as Vogue and Elle and is also the face of label Guess, succeeding the likes of Claudia Schiffer and Alessandra Ambrosio. Alyssa also made her debut in the Sports Illustrated Swimsuit Edition this year.

Next we have Brazilian babe Izabel, 26. The brunette beauty is a former Victoria's Secret Angel and has appeared on the ramp for the likes of Balenciaga, Bottega Veneta and Oscar de la Renta. She has also fronted successful campaigns for Armani Exchange and H&M.

With her brown hair and blue eyes, this 20-year-old American looker is scoring bigtime in the big leagues. Working with the likes of Guess, Givenchy and Maybelline, you'd never guess that Emily was once a smalltown girl who made her a modelling dream come true.

This 22-year-old Pirelli Calendar girl (she featured in the 2009 edition) and Victoria's Secret Angel hails from Brazil. Tall, sultry and with a figure to die for, Emanuela, who also happens to be the face of UK retailer Next, makes it to Number 16.

The Czech cutie, with her blonde hair and green eyes is a mother of one at 27, but has the sizzling bod and fresh faced of a teenager. Karolina is one of the youngest-ever models to have appeared on the cover of Vogue (at the age of 17) and has worked for print campaigns with Louis Vuitton, John Galliano, Chanel, Christian Dior, Tommy Hilfiger, Valentino...the list goes on!

Tied in at the fifteenth spot with Kurkova is Namibian-born Behati, 21. Discovered in a Cape Town supermarket, this pretty woman is now a Victoria's Secret Angel too and already has big names like Chanel, Hugo Boss, Kurt Geiger, Marc by Marc Jacobs, Max Studio and Nina Ricci on her resume.

Twenty five-year-old Russian hottie Anne embarked upon her career a decade ago. She's been appearing in the Sports Illustrated Issue for seven years running now and has also graced the cover of publications like Vogue, Elle, Glamour and Gloss, in addition to fronting prominent campaigns for Louis Vuitton and Prada.

Chalk up another one for the Brazilians. This 28-year-old hottie has done advertisements for Christian Dior, Armani Jeans, L'Or al, Diesel, Victoria's Secret and Chanel cosmetics. In addition, she was also roped in by Jennifer Lopez as the face of JLo Lingerie in 2004.

Another tie -- and another Brazilian to boot. Isabeli Fontana, 27, joins Ana Beatriz at thirteenth place. She appeared in a Victoria's Secret catalogue at 16 and has since been the face of several advertising campaigns for Armani Jeans, Dolce and Gabbana, Escada, Nicole Farhi, Ralph Lauren, Revlon, Roberto Cavalli and Versace, among others.

Hardly anyone needs an introduction to this Israeli siren! The on-and-off girlfriend of Hollywood star Leonardo DiCaprio made her advent into the modelling world at the age of eight months when she started appearing in commercials. Today, at the age of 25, she's one of the best-known faces in the fashion world, having worked with big names like Rampage, Garnier and Passionata lingerie.

Lithuanian looker Edita, 22, has a long list of high-end designers on her list -- Balenciaga, Chanel, Dries van Noten, Miu Miu, and Louis Vuitton, to name a few. Her striking features and 5'9" frame have also seen her become the face of Karl Lagerfeld, GAP in Japan, Dior Beauty and Emporio Armani.

Cristiano Ronaldo's Russian girlfriend has been moving from strength to strength this year, so it's not surprising that she rounds off the top 10 on this list. She landed the Sports Illustrated cover for 2011, a Victoria's Secret contract and has done a sizzling swimsuit spread for Luli Fama. You can expect to see a lot more of her on the style circuit!

Dutch knock-out Lara, 27, was discovered in Paris at the age of 15. She starred in the Pirelli Calendar in 2009, gained worldwide recognition as the face of Calvin Klein and has been signed on to front campaigns for Prada, Louis Vuitton, Jaeger and H&M, among others.

Blonde bombshell Candice is one of Victoria's Secret's best-known faces. At 20, the South African model has already walked the ramp for Tommy Hilfiger, Dolce and Gabbana, Betsey Johnson and Diane von Furstenberg and was voted into 61st place in FHM Magazine's annual '100 Sexiest Women in the World' poll this year.

Twenty four-year-old Rosie is British and is fast becoming one of the country's best-known catwalk queens. In addition to stints with Burberry, Karen Millen, Agent Provocateur, Godiva and Miss Sixty, she has also featured in last year's Pirelli Calendar and been signed on by Victoria's Secret.

She may be married to one of the world's biggest tennis stars, but Brooklyn Decker is making a name for herself on her own merit. At 24, Andy Roddick's beautiful wife has been seen in Teen Vogue, Cosmopolitan, FHM, and Glamour, and has modelled for The GAP, Intimissimi and Victoria's Secret.

Dutch doll Doutzen is 26 and a covergirl several times over, featuring on Time, Vogue, Harper's Bazaar, Seventeen, and Numero. She is, but of course, a VS Angel too and her blonde hair and blue eyes are enough to get any man's heart pumping!

It's but natural that Brazilian hottie Alessandra would fall within the top five. The mother-of-one, 30, is one of Victoria's Secret's most popular Angels and also one of the highest-paid internationally. No wonder ex-supermodel Tyra Banks once called her "the future of the modelling world"!

Orlando Bloom's Aussie wife has earned a lot of brownie points for getting back into fabulous shape within three months of giving birth. At 28, Miranda's certainly got it all -- a Hollywood husband, a bonny baby boy and a career that has seen her reach the pinnacle of success. From magazines like Harper's Bazaar and Cosmopolitan to designers like Balenciaga and Prada, she's done it all.

This Brazilian babe is one of the biggest names in the business. Every magazine worth its salt from Vogue to Harper's Bazaar and every designer from Christian Dior to Louis Vuitton has featured her at some point. Gisele has used her looks to build an empire of millions, even designing her own line of sandals which is the largest-selling Brazilian flip-flop line in the world.

But she still came in at Number Two, so we wonder who toppled her?

Yup, the top spot goes to a Brazilian too, but it's Adriana Lima, Victoria's Secret's top Angel and undisputed sultry siren! From the time she won first place in Ford's 'Supermodel of Brazil' model search at the age of 15, she's been adding to her portfolio -- from Esquire and Marie Claire to Vera Wang and Emanuel Ungaro, you name it, she's done it. At 28 this year, she's right there at the top -- let's see if she is still holding on in 2012!
