TRAVOLTA WON'T SHOW HIS BUTT

Movie star JOHN TRAVOLTA will be shaping up before anyone gets to see his butt in a film. The actor refused to show his behind while filming a nude scene in current film WILD HOGS, because it isn't toned enough. The PULP FICTION star says, "Bill MACy (William H MACey) was the only one who was meant to have a close-up and the rest of us were meant to be in the background. "I don't know if I'm in good enough shape for a nude scene." But he hasn't ruled out the possibility completely. He says, "If I'm ever going to show my booty, I want it to be in good shape and I feel I have more work to do."
