katy perry on the simpsonsFollowing the kerfuffle that accompanied Katy Perry after her online Sesame Street segment got pulled because Katy Perry was dressed like, well, Katy Perry ("EYES UP HERE!"), the pop tart basically punched Elmo in the face by showing up on a live-action segment version of The Simpsons.

In rare form -- as puppets, that is -- and just in time for the Christmas episode, Simpsons characters met the chart-topping, doe-eyed pop star, clad in a tight latex dress featuring the faces of America's favorite animated family. After providing a ssssexy boob-squishing hug to the frigid Mr. Burns, Katy sings a Christmas carol parody with the gang. That's right, she sings! Who would've guessed?
