During a May 25 appearance on The Tonight Show With Jay Leno, Mel Gibson admitted that his girlfriend, Oksana Grigorieva, is pregnant with the actor's eighth child. "We're going to have a baby," Mel confirmed to Jay. "I guess that makes me Octo-Mel," he joked. The actor also took full responsibility for the end of his marriage to Robyn Moore, with whom he has seven children. "My wife and I, our marriage ended three years ago and we've been separated ever since then. It's unfortunate, it's sad, but you know she is an admirable woman — we still got kids together. We're friends," says Mel. "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 added.
