Oksana Grigorieva in Lingerie

Oksana Grigorieva is a Russian singer signed to Mel Gibson's record label, Icon Records. But that's not why you know about her.

In April of 2009, reports came out that she had been carrying on a relationship with the actor, married for 28 years to Robyn Gibson.

This composer and actress formerly dated James Bond star Timothy Dalton. They have one child together, a son named Alexander.

Oksana Grigorieva is 39 years old. In the spring of 2009, it was revealed that she was pregnant with Gibson's child. Pretty scandalous stuff.

Not as scandalous as what happened in 2010, when the couple broke up and she secretly recorded him going insane on the phone.

The two are currently battling for custody over Lucia and face separate police investigations for extortion and domestic abuse.
