Yes, Mark Zuckerberg married Priscilla Chan on Saturday, 19 May at a private ceremony in the grounds of his home in Silicon Valley. The couple have been together since they met while studying at Harvard. It was quite a small wedding with about 100 guests, and they kept it secret until the last moment - in fact the wedding guests were told that the party was actually to celebrate the fact that the bride, Dr Chan, had just graduated from the University of California as a medical doctor (she will practise as a pediatrician). They only heard the truth when they arrived.

The bride wore a traditional white dress with a light veil, and the groom changed out of his famous casualwear to put on a suit.

The appearance of Facebook on the stock market has made Zuckerberg one of the richest men in the world. However, the wedding was quite simple, with sushi and Mexican food at the reception, and a plain ruby ring for the bride.
