Priscilla Chan is now Mrs Zuckerberg.

The 27-year-old has married Facebook billionaire Mark Zuckerberg.

The couple initially met at Harvard and have been linked together for over nine years. They met at a party while waiting in line for the bathroom. 

Priscilla Chan, earned her medical degree on Monday from the University of California. She graduated the same day Zuckerberg turned 28.

"I'm so proud of you, Dr. Chan : )" Zuckerberg wrote on his Facebook page.

Zuckerberg designed the engagement ring himself with "a very simple ruby", according to a company spokeswoman.


Zuckerberg's company, Facebook, began trading publicly yesterday reaching a total value of as much as $122 billion though it dropped later in the day.Even after the IPO, Zuckerberg remains Facebook's single largest shareholder and controls the company with 56 percent of its voting stock. 


Chan told The New Yorker that she thought Zuckerberg was "this nerdy guy who was just a little bit out there."

Since she is Chinese-American, she has triggered interest in Zuckerberg to learn Chinese. They have also been spotted vacationing in the country.

When Chan moved to Palo Alto to live near her boyfriend, she famously made him sign a "contract."

"One date per week, a minimum of a hundred minutes of alone time, not in his apartment and definitely not at Facebook," according to Sarah Lacy's book Once You're Lucky, Twice You're Good.

Zuckerberg previously said Chan wants to be a pediatrician and inspired him to create a new tool on Facebook that allows users to add their organ donation status.
