Katie Holmes Poses Topless for Jewelry Campaign

Wow! The single life certainly agrees with Katie Holmes.

Tom Cruise's ex-wife sheds her clothes in a series of sexy shots for a new IRIS jewelry ad campaign. In one photo, Holmes strips down to nothing but necklace, posing topless with a strategically placed arm. In other pictures, the mother of one looks equally sexy rocking a bikini in the beachy photo shoot.

Ever since filing for divorce from Cruise over a year ago, Holmes, 34, has appeared happier than ever.

Thursday night, Suri's mom stepped out for The New York Observer's 25th Anniversary Party at the Four Seasons Restaurant in Manhattan. Sporting a black mesh dress, Holmes looked gorgeous as she hung out with Katie Couric and Spike Lee.

"Katie seems really happy," her friend, director Adam Shankman, told Us Weekly of the star's single status. "You just fight through all the noise. And it's noisy!"
