London, Nov 7 (IANS) Hollywood star Mel Gibson's girlfriend Oksana Grigorieva has revealed she is confident the actor will never cheat on her.

Grigorieva who gave birth to the couple's first child, daughter Lucia, last week knows her beau is a sex symbol to many women but says he is faithful to her, reports imdb.com.

'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,' she said.

Grigorieva, who also 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.

'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,' she said.

'He is a big kid himself, really - a real practical joker. We laugh so much,' she added.

Gibson already has seven children with his estranged wife Robyn, who he split from in 2006.
