RadarOnline.com, a celebrity news site, has released another audio clip that reveals Mel Gibson arguing with his ex girlfriend and child’s mother, Oksana Grigorieva. In the recording, he calls her a “wetback” and then launches into a stream of profanities. The latest audio file, follows weeks of back and forth between Grigorieva and Gibson. It caught the media’s attention when Grigorieva filed a restraining order against Gibson on June 21. The latest tape was recorded by Grigorieva who says that she recorded it, and the earlier July 9 tape, when she was scared for her life. She later turned them over to use as evidence for Gibson’s criminal domestic violence investigation.
