Mark Zuckerberg, the man who created Facebook whilst studying at Harvard, got married on the weekend to longtime girlfriend, Priscilla Chan.

Just a day after taking Facebook public, the pair got hitched in a low-key, private ceremony in the backyard of their California home, with around 100 guests. The wedding itself was reportedly a surprise to these guests, as the couple had informed them to come over for a 'surprise graduation party' for Chan, who had finished med school the week before.

Zuckerberg, who is now worth more than $19 billion, didn't wear a hoodie, but didn't wear a tux either; just a nice, simple suit. Chan wore an elegant, beautiful dress, and after the ceremony, the couple announced their new status by updating their Facebook pages.
