Facebook CEO Mark Zuckerberg marries longtime girlfriend

Facebook founder and CEO Mark Zuckerberg updated his status to "married" on Saturday.

Zuckerberg and 27-year-old Priscilla Chan tied the knot at a small ceremony at his Palo Alto, Calif., home, capping a busy week for the couple.

Zuckerberg took his company public in one of the most anticipated stock offerings in Wall Street history Friday. And Chan graduated from medical school at the University of California, San Francisco, on Monday, the same day Zuckerberg turned 28.

The couple met at Harvard and have been together for more than nine years.

A source authorized by the couple to speak said Zuckerberg designed the ring featuring "a very simple ruby."
