Mel Gibson's ex Oksana Grigorieva has been approached by Playboy with a $75,000 deal for a "full nude" series of pictures, celebrity website TMZ reported Monday.

Playboy executives are offering Grigorieva a front cover shoot in an attempt to entice her in, sources told the website.

The 40-year-old pianist is currently embroiled in a bitter legal battle with Gibson, 54, over claims he assaulted and threatened her during a series of arguments earlier this year.
