Amazon tycoon Jeff Bezos married Lauren Sanchez in a lavish ceremony on Friday in Venice's San Giorgio Maggiore island.
Sanchez first stepped out from the luxury Aman hotel the couple were staying at, wearing a skirt suit, and Bezos followed some two hours later.
Sanchez's wedding dress was still kept under wraps at the time she hopped onto a motorboat from her hotel, but she later revealed the dress on her newly branded Instagram page with the name: Lauren Sanchez Bezos.
The former journalist reportedly has 27 outfits prepared for festivities over three days, with Dolce & Gabbana having been the fashion house behind her wedding gown.
Bezos wore a black tuxedo and a bow tie over a white shirt, as the official photo Sanchez shared on her Instagram photo showed.
