Katy Perry is Red Hot and Naughty in The Simpsons ‘The Fight Before Christmas’ VIDEO

Katy Perry is at it again!  After the big embarrassment of being booted form Sesame Street, she went all out on the Christmas special for The Simpsons last night.  ‘The Fight Before Christmas‘ episode was not your usual Simpsons holiday episode.

All of the characters were transformed into puppets, like The Muppets and Katy did her thing as Moe’s girlfriend.  And yes, she got dirty at the end.
