Facebook bajillionaire Mark Zuckerberg married his longtime girlfriend Priscilla Chan in a quiet backyard ceremony, and thus far, the couple’s honeymoon has been equally low-key.

Mark and his “swear she’s not a golddigger” wife traveled to Rome for a quiet few days of dining, drinking (just a little – boring!) and strolling through the city’s historic streets. The couple is intensely private, but Mark knows he’s got a few billion fans online, so he didn’t seem to mind when a few paparazzi snapped pics of him and Priscilla. Then again, maybe he went home and banned these dudes from the Internet for life.
