CALIFORNIA — Facebook cofounder and CEO Mark Zuckerberg wed longtime girlfriend Priscilla Chan on Saturday, announcing the nuptials through a status update on the social networking site.

The 28-year-old billionaire’s wedding took place a day after Facebook’s initial public offering on the Nasdaq stock exchange on Friday.

More than 280,000 people “liked” Zuckerberg’s status change, which was accompanied by a photo of the smiling couple in wedding attire in a small, verdant outdoor setting with a string of lights behind them.

In the photo, the famously casual Zuckerberg is wearing a dark blue suit and tie, a departure from his trademark “hoodie,” while Chan has on a sleeveless white dress with lace overlay. Both are smiling for the camera.

Zuckerberg, whose shares are worth nearly $20 billion and who retains voting control of Facebook, marked the debut of his company’s stock at Facebook’s Silicon Valley campus on Friday, symbolically ringing the opening bell for stock trading.

Neither Zuckerberg nor Chan commented further about their marriage on their Facebook pages. The couple adopted a Hungarian sheepdog named Beast a year ago, and live together in Palo Alto, California. — Reuters
