Just six weeks after Mel Gibson's wife filed for divorce, the actor went on the "Tonight Show" to confirm his new girlfriend is pregnant.

"This is true, we're having a child," Gibson said.

Gibson, 53, already has seven children with wife Robyn Gibson, which means the baby would be his eighth.

"I guess I'm Octomel now," the actor joked on Monday night's show.
