The most shocking story of the summer came in audio form: a series of seven leaked tapes, in which actor Mel Gibson is heard threatening and insulting ex-girlfriend (and mother of his infant daughter) Oksana Grigorieva. It's unknown whether Grigorieva leaked the tapes herself, but they became a powerful PR weapon in the ongoing custody battle over 10-month-old Lucia. During the flurry of restraining orders and investigations (on both sides), Grigorieva also accused Gibson of punching her in the face while she held their child -- and claimed she had dental records of her broken teeth. The domestic violence case against Gibson is still ongoing. As for whether he'll work in Hollywood again -- the jury's out on that, too.
