This wouldn’t be the first time they’ve kissed and made up. Penn, 48, and Wright Penn, 43, launched a divorce action in the same court in December 2007 only to yank the petition four months later. This time around, Penn asked the court for joint physical and legal custody of their children, daughter Dylan, 18 and son, Hopper, 15. He also asked the judge not to give any spousal support to his wife. Friends say, “They love each other like crazy but they fight like crazy. They may have gotten into a fight where she said she wanted a divorce and he filed just to beat her to the punch, even though he doesn’t want a divorce. That doesn’t mean they’re suddenly happy and in love. It’s anyone’s guess where this is going.”

Robin at the Cannes Film Festival

Natalie Portman recently denied rumors that she was “romantically involved” with Penn, calling him “a friend and colleague.” Penn has been in New York shooting, “Fair Game,’ in which he plays former Ambassador Joseph Wilson, husband of CIA agent Valerie Plame. Meanwhile, Robin is at the Cannes Film Festival flying solo. Every time she’s hit the red carpet, she’s looked like a million bucks. Maybe he saw that and realized he didn’t want to loose her. Who knows?
