Now you see her, now you don't.
Oksana Grigorieva, the beautiful Russian singer who has been secretly dating Still Married Mel Gibson since at least last year, has gone into hiding, RadarOnline.com has learned exclusively.
The affair first became public with our exclusive photos of the couple embracing passionately in Costa Rica earlier this year.
RadarOnline.com was first to solve the mystery of Oksana's identity when we revealed she is "James Bond" star Timothy Dalton's ex-girlfriend and the mother of his son. (Various reports named three other Oksanas as the girflriend.)
Mel bought a house in Sherman Oaks in December 2008 and Oksana and her son moved in a month later, RadarOnline.com learned exclusively.
The house has four bedrooms. It was purchased in the name of one of Mel's top executives.
Now, while other PEOPLE in the media try to take credit for our scoop on the real Oksana, we can reveal exclusively that she has gone into hiding.
And in a curious twist to the Mel Madness, RadarOnline.com discovered Oksana went into hiding shortly BEFORE Mel's wife Robyn filed for divorce!
Neighbors at the Sherman Oaks, Calif. home told RadarOnline.com that Oksana had been living there with her son but disappeared a few weeks before the Gibson divorce papers hit. One of her cars is still there.
So where in the world is Oksana? Keeping a very low profile for now but still romantically linked to Mel, who simply does not want to discuss the situation.
His $900 million divorce has already shown public signs of becoming contentious, with Mel claiming he and Robyn split three years ago, but Robyn saying that date is to be determined later in the proceeding. The date of the split could effect how much money Robyn receives.
