Even Michelle Williams Has Katy Perry's 'I Kissed a Girl' Stuck In Her Head

You're not the only one with the chorus of Katy Perry's "I Kissed a Girl" stuck in your head on repeat -- it's even lodged in Michelle Williams' pretty little head too. Find out what else she's listening to this summer, besides Usher's "Love In This Club" ode to PDA, Jordin Sparks and Chris Brown's "No Air," and Rufus Wainwright (a Buzzworthy favorite!)... again, more "unexpectedness" from Michelle Williams, who is a human iPod Shuffle.

+ Plus, watch Michelle reveal the naughty bits you won't see in her "We Break the Dawn" video, and check out Katy Perry backstage at TRL and on FNMTV (in a panda dress, no less!)
