Priscilla Chan has long been known as the girlfriend of Facebook founder Mark Zuckerberg, but on last Saturday she updated her status to the billionaire’s wife. Mark Zuckerberg and Priscilla Chan are finally married after dating on and off for nine years, since the couple’s Harvard days.

The bride wore a $4,700 Claire Pettibone dress… but all eyes weren’t on Priscilla Chan’s wedding gown: they were on Mark Zuckerberg’s suit – proof the man does own something other than a hoodie. The facebook founder married his girlfriend of nine years this weekend in a surprise ceremony in his backyard.
