Mel Gibson Roars Sex Demands in Fourth Telephone Attack on OksanaIn RadarOnline.com's fourth blistering Mel Gibson audio rant, the actor literally roars (think tape two) for oral sex while threatening to burn the house down.

"I deserve to be b***n first! Before the f***ing Jacuzzi! Okay? I'll burn the goddamn house up, but b**w me first!" Gibson, 54, thunders, so enraged that he's left panting for breath.

Oksana Grigorieva, 40, also apparently sought the number of Gibson's therapist, giving him more ammo to unload. "Don't you ever speak to him! Find your own g*****n therapist! Because you've got problems more than me!"

Oksana maintains supreme calm throughout the new three-minute tape.
