Oksana Grigorieva?

Oksana Grigorieva is a 39-year-old Ukranian opera singer. She has been named in Mel Gibson's divorce papers, and is signed to his record label, Icon.

Hmm. The mother of my seven children, or a hot Russian model who plays the piano in her underwear.

This, apparently, was Mel Gibson's dilemma.

Oksana Grigorieva is the alleged "other wo-man" being reported as the final straw that broke the back of the Gibsons' 29-year-long marriage.

Now new racy lingerie photos of the model/pianst doing the two things she does best, all at the same time, have surfaced on gossip site Radaronline.com.

Grigorieva has been with Mel since at least last year, and was photographed embracing him in Costa Rica earlier this year, according to the site, which reports she has since been put up in a four-bedroom house paid for by the "Braveheart" star.

Mel's wife Robyn filed for divorce earlier this month, but Gibson says they have been separated for two years.

Oksana is also the mother of former "James Bond" star Timothy Dalton's son.
