Ashton Kutcher and Alessandra Ambrosio for Colcci: Photographed by Steven Klein, the 2010 Colcci jeans Fall/Winter ad campaign shows a very slick Ashton Kutcher, Demi Moore’s toy boy husband, lying besides an equally glossy-looking Victoria Secrets Angel Alessandra Ambrosio. So hot.
Natalie Portman for Christian Dior: Natalie Portman poses in nothing but a black bow headband for the new Miss Dior Cherie perfume ad. The 30-second ad shows the Hollywood actor roaming the streets of Paris and ends with Portman lounging across a sofa removing a bowtie from her neck while the perfume’s signature bottle rests on a pillow nearby.
Kate Winslet for Lancome: Kate Winslet, remembered for her nude scene in Titanic, bares all again for the Lancome L'Absolu Nu ad. Winslet wears nothing but a shade of the luxury lipstick and a sheet in this sexy ad.

Tamara Mellon for Jimmy Choo: Not too many CEOs will pose sexily to promote their products. But Mellon, who heads the luxury shoe brand chose to expose her d├ęcolletage (very tastefully) in an ad for Jimmy Choo’s first fragrance.

Megan Fox for Armani: Megan Fox has posed provocatively in jeans and a bra-and-panty set in in Armani’s the new Summer/Spring 2011 ad campaign. Fox, who is the face of Armani jeans and underwear for women, is seen as a worthy successor to Victoria Beckham by many.

Raphael Nadal for Armani: He might have replaced the more chiseled Christiano Ronaldo, but tennis ace Raphael Nadal manages to smoulder rather sexily in Armani’s jeans/briefs ad campaign.
Julianne Moore for Bvlgari: This Bvlgari ad is so hot, it’s actually been banned in several countries. We guess looking at Julianne Moore in nothing but Bvlgari accessories and a few lion cubs to cover her modesty was just too much.
Scarlett Johansson for Moet & Chandon: GQ magazine’s Babe of the Year 2010 stands up to her title in the ad for luxury champagne brand Moet and Chandon. The 2011 ad campaign shows the Iron Man 2 star draped in a sexy white gown, surrounded by bottles of Moet champagne. Scarlett Johansson has been the brand ambassador for the champagne brand since 2009.
Kirsten Dunst for Buvlgari: Bulgari loves to sit pretty women and big cats next to each other in its ad campaigns. The svelte Kirsten Dunst poses in nothing but a satin sheet, with a lion for company in Bulgari’s Mon Jasmin Noir perfume ad. The Spiderman star does ‘sexy’ very, very well.
Chris Evans For Gucci: Chris Evans, of Captain America and Fantastic Four fame, oozes raw sexuality in Gucci’s Guilty for Men perfume ads. A hirsute Evans is a nice change from the otherwise too-perfect male models we usually see in such ads.
