Avril Lavigne Has A Fat Ass

As the world debates whether Avril Lavigne is pregnant or not, TMZ.com is trying to help solve the mystery.

The celebrity site posted a 20-second clip on Wednesday of Lavigne and hubby Deryck Whibley, where a cameraman says to Lavigne, "I don't know what they're talking about. You don't look pregnant at all."

"Yeah, I have such a fat ass," replies the pop tart.

"You're not a fat ass," says the cameraman as Lavigne laughs. Whibley, mimicking his recent music career, does nothing.

Perhaps Lavigne didn't realize that Hilton pointed out that her stomach was fat, not her ass. Maybe she doesn't know the difference.
