The $375,000 Interview with Oksana Grigorieva

When Oksana Grigorieva chose to speak of her ex Mel Gibson to Howard Stern, she made a big mistake, one that will cost her $375,000, according to a Friday report from TMZ.

Under the her agreement with Mel, the singer was not supposed to discuss him at all. The comments were made four months ago, but only now has a judge decided they were in violation of that agreement, according to TMZ.

Oksana Grigorieva was receiving payments as part of the $750,000 settlement with Gibson after a nasty split in 2010 that included claims of physical abuse and a leaked tape recording where the actor belligerently berates her.
