Gisele Bundchen and Tom Brady attended the Costume Institute Gala last Tuesday, but aside from her gorgeous gown, all eyes were on her wedding ring. Bundchen actually opened up about her two weddings to the New England Patriots' quarterback. The couple said their vows in a small and intimate Catholic ceremony in LA at dusk with only immediate family attending, including Tom's son, John Edward Thomas Moynahan, and also in a super-secret ceremony last month in Costa Rica. Gisele wore a strapless gown by Dolce & Gabbana, which also made her three dogs' lace collars, which they wore.

"We tried very hard to keep it private. Oh my God, you have no idea how hard that was," Bundchen told reporters at the Costume Institute Gala. "I think family is the base to everything. I have a lot to be grateful for but I think family is definitely number one."

Bundchen might be newly married, but Sean Penn and *Robin Wright Penn*'s marriage might be over...again. Star Magazine reports that Sean filed for a legal separation from his wife in April, and in the meantime, he's been spotted getting cozy with actress Natalie Portman. The two allegedly met after serving on the Cannes Film Festival jury. Portman is 27 and Penn is 48; not that age matters. But does it matter if one person is married when you start to date? Portman and Penn reportedly started up their love affair while Penn was still married back in March. Star reported the two had dinner at Sunset Tower Hotel's Tower Bar and were "constantly touching each other." After dinner, they took elevators that went to the hotel's spa and private rooms.

What does Ms. Britney Spears demand for her hotel room while traveling on tour? Among her requests, according to USA Today, a room that has "never" been smoked in, fresh flowers, humidifiers in all areas, Marilyn Monroe movies on DVD, a variety of current magazines, chick-lit novels and 100-watt light bulbs, among other things. She won't need special pillows because she will bring her own. And security allegedly sleeps outside her room! All in the name of protecting the starlet, we guess.

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.
