Mel Gibson Racist Rant Audio Tape PART 3: 'F**king Whore,' 'Wetbacks' & More

Radaronline.com has released a third terrifying tape of Mel Gibson raging against his ex, Oksana Grigorieva.

"You're a f*cking mentally deprived idiot," Mel screams on this tape. "You're a f*cking using whore...I own you. You don't count."

He also hurls an ethnic slur--wetbacks, in reference to a Hispanic staffer.

"I will fire (name omitted) if she's at your house," Mel tells Oksana. "I will make it known and fire her. I'll report her to the f *cking people that take f *cking money from the wetbacks, ok?"

Towards the end of the bitter argument they fight over their eight-month-old daughter, Lucia.

"Go look after my child!" Mel screams.

"She's my child too," Oksana responds.

"Yeah I know, unfortunately you c*nt whore! I hope she doesn't turn out like you!"

Monday a tape surfaced in which Mel threatened to kill Oksana and told her to 'f**king blow me,' alternately screaming at her and breathing heavily. Radar release the first tape, containing Mel's n-word rant, on Friday.

Oksana's dentist took pictures of her mouth after Mel allegedly knocked her teeth out during a January 6 dispute, TMZ reports. The dentist will be a key witness in the domestic violence case.
