Drama certainly seems to follow Mel Gibson everywhere. The 54-year-old actor filed a restraining order against his ex-girlfriend and mother of his 7-month-old daughter, RadarOnline.com reported Friday. Gibson and his 40-year-old girlfriend Oksana Grigorieva split in April, but on Thursday, he filed legal documents in Los Angeles Superior Court for a temporary restraining order, a notice about an upcoming court hearing, and a notice about visitation rights and child custody. Though the case is sealed, Radar claims the complaint centers around the actor’s access to Lucia, his daughter with the Russian singer. People magazine reported Friday that Grigorieva accused Gibson of hitting her, but a source says Gibson was allegedly stepping in to stop her from injuring their daughter. The source claims she then withheld the child from the actor on Father’s Day weekend, despite a reported scheduled visit. “He’s playing dirty,” Grigorieva told Radar on Friday. “The truth will come out.” Gibson’s rep did not offer comment.
