Mel Gibson’s new girlfriend is reportedly pregnant, according to

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 Gibson, 53, has already told Robyn and their children the news, although it wasn’t well received.

A source told the National Enquirer magazine: “In late April, Mel gathered his children at the family home in Malibu and broke the news that Oksana is pregnant, and he expects them to accept the baby as a new sibling.

“They are quite upset. Even though Mel assured them the pregnancy was unplanned, they’re furious with him, and say they’re going to take steps to protect their inheritance, which they feel is in jeopardy.”

Robyn filed for divorce in April, citing “irreconcilable differences,” and she is expected to get half Gibson’s fortune.
