George Clooney and Amal Alamuddin are legally married.

The couple - who tied the knot in Venice, Italy on Saturday (27.09.14) - underwent a civil ceremony at Palazzo Ca'Loredan, an official council building in the city, earlier today in accordance with Italian laws.

The ceremony was officiated by the 'Monuments Men' star's friend, former Rome Mayor Walter Viltroni, who also presided over the wedding on Saturday.

George wore a grey suit for the service, while Amal, 36, donned a simple cream trouser suit and floppy hat and the pair - who travelled to the venue in the same Amore boat they have used all weekend - exchanged their vows in the stunningly-decorated Sala Degli Affresch room.

The 53-year-old actor's favourite taxi driver, Alessandro Greco, was an official witness.

Speaking as he emerged from the building, smiling George told Us Weekly he felt ''very good''.

The weekend-long celebrations began on Friday (26.09.14) with bachelor and bachelorette parties, with their wedding taking place at the luxury Aman Canal Grande hotel on Saturday.

Yesterday (29.09.14), the couple hosted lunch at the Belmond Hotel Cipriani, where most guests had been staying and then they celebrated with another party in another area of the hotel later in the evening.
