In 2012, Mark and Priscilla arranged a secret wedding that they hadn’t even informed their guests about. Thousands of celebrities were invited to the Zuckerberg’s house in Palo Alto to celebrate Priscilla’s graduation from the University of California. Suddenly the couple appeared in front of their guests in their wedding attire. The guests were treated with sushi and barbeque right in the backyard of the house. Additionally, Mark presented his wife a ring he had designed himself.
