Mel Gibson's new girlfriend is reportedly pregnant. The "Lethal Weapon" star - who already has seven children with estranged wife Robyn - and Russian singer Oksana Grigorieva are said to be expecting their first child together in the autumn.

It has been claimed Mel, 53, has already told Robyn and their children the news, although it wasn't well received.

Mel Gibson made his first public appearance with his new girlfriend Tuesday night - just two weeks after his wife filed for divorce. The "Lethal Weapon" star was accompanied by Russian pop star Oksana Pochepa at the Los Angeles industry screening for "X-Men Origins: Wolverine" at Hollywood's Grauman's Chinese Theater.

An onlooker said: "They came in as quietly as they could and tried to be pretty low-key. You could tell they didn't want to attract too much attention, although Mel seemed very comfortable with her."

Mel Gibson's children are refusing to talk to him. The 'Braveheart' actor's seven kids are said to be furious at their father's separation from their mother Robyn Moore Gibson - who he wed 28 years ago - and do not want to have any contact with him.

Mel's Malibu neighbour said: "The children are totally furious about the collapse of their parents' marriage. None of them are talking to their dad right now. They are very upset.

Mel Gibson has been romantically linked with six women - including Britney Spears. The "Lethal Weapon" star - whose wife of 28 years, Robyn Gibson, filed for divorce on Friday - has been seen with a string of women over recent months, including the 27-year-old "Womanizer" singer.

Marital tensions reportedly worsened when the 53-year-old actor let Britney use his Costa Rican home last year.

Mel Gibson's alleged lover says their romance is "serious." Russian pop star Oksana Pochepa claims she is having a relationship with the "Lethal Weapon" star - whose wife of 28 years, Robyn Gibson, filed for divorce on Friday - and believes their love will last.

The 24-year-old beauty said: "This is serious and I hope that our union will be real and strong and long-lasting."
