While Michele's pics are certainly racy, she doesn't mind stripping down. In fact, the singer has created her own "bed series," in which she posts sexy snaps of herself laying in bed -- often in the nude.

"Mario Testino has the towel series. He has celebrities taking pictures in towels, so I did my lamer version, the bed series, of traveling all the time and being in different beds," she explained on The Ellen DeGeneres Show last month. "It started sort of simple, and then it became more and more naked. And more and more calls to my dad having to explain to him what he might see."
