Facebook founder and CEO Mark Zuckerberg capped off a busy week by getting married today to longtime girlfriend Priscilla Chan.
The couple, who met at Harvard and have been together for nine years, tied the knot in a small ceremony at Zuckerberg's house in Palo Alto, Calif.
Chan, 27, has been busy this week too -- she graduated from medical school at the University of California, San Francisco on Monday.
A company spokeswoman said the ring featuring "a very simple ruby" that Zuckerberg designed himself.
