The actor married human rights lawyer Amal Alamuddin on Saturday in a very private ceremony in Venice, Italy.
Their union will be formalized Monday by the former mayor of Rome, Walter Veltroni, Reuters reports.
After a big party on Friday night, George joined his guests on Saturday morning as they crossed the Grand Canal to reach the place of the ceremony, the 7-star Aman hotel.
The actor, dressed in an Armani suit, and his new wife, who stunned in a gown by designer Sarah Burton for Alexander McQueen, greeted fans and photographers who had invaded the Grand Canal and its surroundings.
Celebrity guests like Matt Damon, Bono, Ben Affleck, Cindy Crawford, Anna Wintour and Emily Blunt all made the trip to see Clooney marry Alamuddin.
Propelled to the status of international s-x symbol thanks to his role in “ER”, Clooney promised to never marry again after his divorce from Talia Balsam in 1993.
International lawyer Amal Alamuddin has worked for former Secretary General of the UN, Kofi Annan, former Ukrainian Prime Minister Yulia Tymoshenko and Julian Assange, founder of Wikileaks.
George, 53, and Amal, 36, became engaged in April after first being photographed stepping out together in London in October 2013.
