Mark Zuckerberg got married, everyone! A day after taking Facebook public, Zuck tied the knot with his longtime girlfriend Priscilla Chan and announced it the only way he knows how: through his Facebook timeline

How the ceremony came together is actually adorable. Zuckerberg and Chen had been planning the wedding in secret for five months months leading up to this weekend, according to All Things D. The timing of the wedding lining up with Facebook's IPO was just a coincidence. The date of the IPO was a "moving target" and just happened to coincide with the wedding. The ceremony was held in the backyard of Zuckerberg's California home. He even designed the ring himself!

The 100 attendees thought they were attending a party for celebrating Chen's recent graduation from med school, and Mark's birthday, which was on May 14. The couple didn't tell their wedding guests they were attending a wedding until everyone had arrived. "Everyone was shocked," a source told The Associated Press, who were the first to report the story. 

Congratulations, guys!
