Top 10 Sexiest Ads 2011: Rihanna, Miranda Kerr, Kate Moss Make Top Three [PHOTOS]

Rihanna's Armani Jeans ad campaign has been dubbed the Sexiest Ads of the Year in a poll conducted by Advertising Age magazine.

The 23-year-old sizzled in the photos for the acclaimed Italian designer. In one shot, she appears draped in a town-car wearing nothing but a bra and panties. In the other, she folds herself over the hood of a car wearing a leather jacket, a bra and jeans. Rihanna sported chopped platinum hair and a taut, toned body.

It's Rihanna at her sexiest. She's never looked this good, Ad Age said. Adding, She's in amazing shape and the pictures are stunning.

New mother Miranda Kerr came in second with her first spread for Victoria's Secret post-baby, mere weeks after giving birth to son Flynn. Kerr had taken a break from modeling while she was pregnant with her and husband Orlando Bloom's first child. Following the birth, she whipped herself into tip-top shape and looked absolutely breathtaking.

Ad Age called her fabulous and said It's like she's never been away.

British supermodel Kate Moss came in third place for her topless campaign for Italian clothing company Liu Jo. Gisele Bundchen came in fourth for her Hope lingerie ads, looking gorgeous after having her first child, Benjamin, with husband Tom Brady. Irina Shayk clinched fifth place thanks to her ads for U.S. swimwear brand, Luli Fama.

Ad Age said that Shayk was in massive demand in 2011. Obviously, her relationship with Ronaldo has put her in public eye and everyone wants a piece of her.

Heidi Klum came in sixth for the editorial promotions for her hit reality show Project Runway. Pamela Anderson took seventh place for her sensual advertisements for the stockings company Secrets in Lace. Model Lily Aldridge, who is newly married to Kings of Leon rocker Caleb Followill, came in eighth for her stunning campaigns with Victoria's Secret.

Israeli model Bar Rafaeli took ninth for her Passionata underwear shots and Kate Upton rounded off the top 10 with her shoot for Jenna Leigh Lingerie.
