That turned ugly fast: Oksana Grigorieva has filed a restraining order against Mel Gibson. Though no details have been made public, Mel also reportedly filed a restraining order against her. The couple, who have a 7-month-old daughter, Lucia, together, ended their one-year relationship — which reportedly caused the demise of his 28-year-marriage — in April. "I can tell you that we have split up, suddenly and recently," Oksana said at that time. "Unfortunately, I cannot give you the reason. But you will find out everything quite soon."
