In the crazy world of celebrities, this week is all about love gone wrong and legal misadventures. According to People magazine, Jon and Kate of TV's Jon & Kate Plus Eight are fending off new rumors that their marriage is on the rocks, after Jon was spotted out with an alleged female "friend" late one evening. Although he claims it was strictly platonic, he released a statement apologizing profusely for his "poor judgment." Seems dealing with their eight kids has Jon a little confused.

Actor Sean Penn also filed for divorce this week from his wife of thirteen years, actress Robin Wright Penn. Although the couple has started and stopped divorce proceedings before, it looks like this time it will stick: Penn was seen with model Petra Nemcova during the separation. The couple are seeking joint custody of their two children, daughter Dylan, 18, and son Hopper, 15. And Mel Gibson, who is in the middle of a divorce, has wasted no time moving on to the woman of his (mid-life crisis) dreams. He showed up at the Wolverine premiere with his Russian lover, Oksana Grigorieva, 39. At the premiere, Gibson looked much older than his fifty-three years. I suppose the end of a 28-year marriage, having seven kids and going crazy will do that to you.

In legal news, singer and alleged woman-beater Chris Brown is trying to get the assault charges against him dismissed in the vicious beating of singer (and quasi ex-girlfriend) Rihanna. The reason for his attempt at a dismissal? Not that he didn't do it, or that there's not sufficient evidence - he's trying to get the charges dropped because of the leaked photo showing the bloody and battered face of Rihanna after the incident. Say what?

That's the low-down on the top celebrity gossip this week. From infidelity to Gibson's younger Russian lover, celebrity news just goes to show you that some things never change.
