Mel Gibson confirmed that his girlfriend Oksana Grigorieva is pregnant in a colorful appearance on NBC's Tonight Show with Jay Leno. Leno jokingly asked if that would be the 29th kid for the actor. "Well, actually eight. I guess I'm Octo-Mel," Gibson responded. The actor also talked about his divorce with ex-wife Robyn: "Look. When it's all said and done, I did a pretty good hatchet job on my marriage myself. I'm to blame. If you're inclined to judge, put it here," he said. Gibson is one of the special guests lined up for Leno's last week with the show before Conan O'Brien takes over June 1.
