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 home in Palo Alto, California 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.
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 authorised by the couple to speak said Zuckerberg designed the ring featuring "a very simple ruby."
The ceremony took place in Zuckerberg's backyard in front of fewer than 100 guests, who all thought they were there to celebrate Chan's graduation.
