Tom Cruise's ex-wife Katie Holmes 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.
