It's been a big weekend for Mark Zuckerberg. On Friday, Facebook (the company that he founded from his college dorm room) went public in the third largest initial offering in history, and today he married his longtime girlfriend Priscilla Chan.

As we reported earlier this week, Mark and Priscilla have had their problems in the past, but the Zuck apparently decided to celebrate his newfound mega-wealth by making an honest woman of Chan. It's been a month of accomplishment for one of the world's youngest power couples, as May also marked Priscilla's graduation from veterinary school.

Mark and Priscilla have been dating since 2005, before he became a multi-billionaire. Still, we hope dude has a hell of a prenup. Congrats to the happy couple, and our condolences to anyone who had to think of a wedding present for this guy.
