Oksana Grigorieva began taping her ex Mel Gibson’s rages over the phone on February 18, when the actor flew into a jealous rage because he thought Grigorieva was sleeping with the landscaper. Gibson had come over to visit on the same day he quit smoking, putting him in a terrible mood. Suspecting she was having an affair with the person he referred to as the “tree man,” Gibson feared he would hurt Grigorieva and his kid, so he left. Then the phone calls—and the taping—began. TMZ reports that all the recordings were made on that single day.
