Facebook founder Mark Zuckerberg and his wife Priscilla Chan were spotted during their honeymoon in Rome by a tourist who posted their photo on Twitter.
The Polish tourist Darek Rusajczyk clicked a photo of the newlyweds during their private tour in the Vatican's Sistine Chapel.
An unnamed employee at the noted Pierluigi Restaurant told the media that on Sunday the billionaire couple had an "intimate and romatic fish dinner" of oysters, fish carpaccio and Catalan shrimp salad as an appetizer.
The meal was followed by pasta with lobster sauce and concluded it with John Dory fish.
Mr Zuckerberg and 27-year-old Priscilla Chan tied the knot at a small ceremony at his Palo Alto, California, home last week.
The ceremony took place in Zuckerberg's backyard before fewer than 100 guests, who all thought they were there to celebrate Chan's graduation.
The famous Facebook founder recently even updated his status on the social networking site to 'Married' from 'Single'.
