Well, she got into trouble with some Muppets. Now, let's see if Katy Perry can get in trouble with some Simpsons. A few months back, the pop singer was famously cut from an installment of 'Sesame Street,' after her low-cut outfit offended some parents and was deemed too "cleavage-y."

But Katy landed on her feet, and is back on the new Christmas-themed episode of 'The Simpsons' (Sun., 8PM ET on Fox). And she's wearing a form-fitting red dress that shows off about the same amount of décolletage. Lucky, this is prime-time on Fox, not the middle of the afternoon on PBS, so she shouldn't get banned this time around.

To complete the parody, the Simpsons are transformed into puppet versions of themselves (the context is a dream that baby Maggie has about a 'Muppets'-style DVD). In a set-up worthy of 'The Muppet Show,' Homer has lied to his boss in order to give the family a Christmas vacation to Hawaii. But then, mean ol' Mr. Burns shows up at their house ... Will Katy Perry be able to save the day? Or at the very least, will she manage to sexily grope some puppets?
