The founder of Facebook ended a busy week, which saw his company valued at $106bn after a stock market flotation, by getting married.

Mark Zuckerberg, who's the CEO of the world's most popular social networking site, wed his long-term girlfriend Priscilla Chan. The 27-year-old bride had a hectic week of her own, having graduated from medical school.

The wedding ceremony was a low-key event. It took place in Zuckerberg's garden in Palo Alto California and was attended by fewer than 100 guests, who came along thinking they were there to celebrate Priscilla Chan's graduation.

Displaying his flair for innovation, Mark Zuckerberg designed the wedding ring himself. It's described as a "very simple ruby".

The couple met at Harvard University nine years ago, the year before Zuckerberg launched his business in 2004. They later moved to California, where Facebook has its headquarters.

The multi-billionaire listed his company on the Nasdaq stock exchange on Friday. Facebook's valuation after its flotation means the site is worth about the same as the internet shopping site, Amazon, and more than corporate giants such as Disney.

Even after the flotation, Zuckerberg continues to control just under 56% of the voting power of the company.
