Joan Rivers cake-bombed, Miss Piggy fight! [PHOTOS]: 'Fashion Police' comedian slammed with dessert at Oscars party [VIDEO]

Joan Rivers surprised fellow partiers when she ran out of a QVC pre-Oscars bash covered in sticky frosting and cake!

But no worries, it was all just an innocent prank.

Apparently, Miss Piggy thinks that the "Fashion Police" comedian has way too much plastic surgery done. "The Muppet Show" diva makes fun of Rivers' overly "fake" look, and the two get into a mini-scuffle. Suddenly, the 80-year-old actress gets thrown into a massive cake!

Check out photos of Rivers, running out of the event with frosting running down her face and wardrobe.

Several fans might remember that last year, Rivers let songstress Fergie pie her in the face on an episode of "Fashion Police."

Apparently, Rivers is a huge fan of dessert (just not necessarily eating it)!
