Someone threw a cake at Joan Rivers on a red carpet Friday night -- and let's face it, with as many celebrities as she's dressed down over the years on E!'s Fashion Police, pretty much everybody in Hollywood is a suspect.
England's The Daily Mail reports that the comedian was attending a party thrown by QVC, which sells her jewelry line when she got a face full of yellow cake and white icing. No one saw the pastry bandit.
Rivers, 80, ran back to her car and that was that.
