London, July 18 - Oscar winning director-actor Mel Gibson's wife Robyn seems to have moved on after her marriage to him failed.

Contactmusic.com reports that Robyn filed for divorce April this year citing 'irreconcilable differences'.

They were married for 28 years. But it was revealed later that the two split in 2006, after Gibson was arrested for drunken driving.

Gibson also announced recently that his Russian lover Oksana Grigorieva is expecting his child.

But Robyn has also moved on. A source said: 'Robyn is in love and having the time of her life with a new guy from northern California. She's introduced him to her children and they think he's great. But she's downplayed the relationship. She always introduces the guy as her friend.'
