Mel Gibson's girlfriend is confident he will never cheat on her.
Oksana Grigorieva - who gave birth to the couple's first child, a daughter Lucia, last week - knows her beau is a sex symbol to many women but says he isn't interested in that.
She said: "If he wanted to go down that road he probably would have done so by now, and I think he is a very solid and faithful person."
Oksana - who has a 12-year-old son Alexander from her relationship with actor Timothy Dalton - says she was attracted to the 53-year-old star mainly because of his sense of humour.
She added to Britain's Glamour magazine: "I thought he was wonderful - and, of course, extremely handsome. Also so versatile as an actor and a very talented director. But what I really liked was how funny he could be.
"His a big kid himself, really - a real practical joker. We laugh so much."
Mel already has seven children with his estranged wife Robyn, who he split from in 2006 but divorce proceedings weren't started until earlier this year.
