(The Blaze/AP) -- Mark Zuckerberg has updated his Facebook status to "married," literally.
The 28-year-old Facebook founder and CEO has wed longtime girlfriend, 27-year-old Priscilla Chan, capping a busy week for the couple. His Facebook profile page showed the two married Saturday and included a photo of the newlyweds.
Zuckerberg took his company public in one of the most anticipated moves 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.
Even after the IPO, Zuckerberg remains Facebook's single largest shareholder with 503.6 million shares, and he controls the company with 56 percent of its voting stock.
The ceremony took place in Zuckerberg’s backyard before fewer than 100 guests, who all thought they were there to celebrate Chan’s graduation.
While details of the event are scarce, a company spokeswoman said Zuckerberg designed the ring himself to feature “a very simple ruby.”
The move already has more than 200,000 "likes" on Facebook.
