Katy Perry, Cleavage Guest Star On 'The Simpsons' (VIDEO)

Katy Perry's cleavage finally got to co-star with puppets on television. A month after parental objections shelved her racy singalong with Elmo on Sesame Street, the 'California Gurls' singer made a spoof appearance on 'The Simpsons' in another low cut gown.

In the live action clip, Perry plays bartender Moe's girlfriend, giving the puppet a very intimate hug to Mr. Burns - who gleefully responds, "I kissed a girl and I liked it," a reference to Perry's first hit song.
