Los Angeles, California (CNN) -- Audio released Friday purportedly captures an argument between Mel Gibson and ex-girlfriend Oksana Grigorieva, in which he launches into a racist, sexist rant against her. RadarOnline released the audio, claiming the male voice is that of 54-year-old Gibson. CNN has not independently confirmed the authenticity of the tape and the voices on it. At one point on the roughly two minute tape, the man says: "You go out in public and it's a f***ing embarrassment to me. You look like a f***ing b**** on heat and if you get raped by a pack of n***ers it will be your fault."
