Like the three tapes that have preceded it, the three-minute conversation, streaming on RadarOnline, finds the actor-filmmaker, 54, outraged and explicit, screaming at Grigorieva, 40. "How dare you act like such a bitch when I'm being so f---ing nice," he reportedly says.
The two appear to be arguing about having sex, and Gibson, seemingly upset that Grigorieva fell asleep, screams, "I'll burn the g-----n house down," before graphically demanding oral sex.
He also discloses that he's seeing a therapist, but tells his girlfriend, "You wanted the number of my therapist? Don't you ever speak to him. … You've got problems more than me."
Grigorieva speaks up, responding, "You need medication."
Earlier this year, Gibson sought therapy to deal with his relationship with the Russian musician, with whom he has a 9-month-old daughter, Lucia.
