You can see the pleasure in Mel Gibson's face as he left a restaurant in Malibu Friday. He didn't want to talk about Oksana Grigorieva and the fact that she has gone belly up ... filing for bankruptcy. But you can see a certain peacefulness and calm that hasn't been exactly front and center.
As we previously reported ... Oksana could have been set for life if she didn't reject Mel's $15 million settlement back in the day, when those tapes were just between them. But she got greedy, and ended up with $750K and lots of lawyers bills. And half of that money was taken away because she blabbed about Mel ... violating their confidentiality agreement.
Fact is ... Oksana is still riding Mel's gravy train. He's paying $20K a month for child support, and that will likely last until Lucia turns 18.
