Facebook CEO Mark Zuckerberg got married on Saturday to his longtime girlfriend Priscilla Chan, but if the happy couple wants to stay together, they might want to consider staying off of Facebook.

According to a U.K. survey by Divorce Online, a legal services firm, more than a third of divorce filings last year contained the word "Facebook," reportsSmartMoney magazine.

Over 80% of U.S. divorce attorneys say they’ve seen a rise in the number of cases using the word "social networking," according to the American Academy of Matrimonial Lawyers.

K. Jason Krafsky, who co-authored the book 'Facebook and Your Marriage,' with wife his Kelli, toldSmartMoney: “Office romances and out-of-town trysts can take months or even years to develop. Affairs happen with a lightning speed on Facebook. It puts temptation in the path of people who would never in a million years risk having an affair.”
