George Clooney has tied the knot with British-Lebanese lawyer Amal Alamuddin in Venice, a representative for the actor has confirmed.

The wedding was originally thought to be taking place on Monday.

The actor's closest friends including Bill Murray, Cindy Crawford, Matt Damon, Emily Blunt, U2 frontman Bono and John Krasinski joined the couple for the lavish wedding ceremony at a Venice palace on the city's Grand Canal.

The groom arrived on a motor launch flanked by around 20 other boats carrying photographers, local police and cheering onlookers. Looking suave in a tuxedo he made his way to the Aman Canal Grande Venice, for the wedding.

Described as looking excited and nervous all at once, the star was accompanied by his mother and father, Nina and Nick, and members of his extended family.

The couple had earlier requested that guests do not bring mobile phones in a bid to prevent unauthorised pictures being leaked from the event.

The couple were earlier spotted together in high spirits during an al fresco breakfast outside the Belmond Hotel Cipriani.

They were joined by supermodel Cindy Crawford, 48, and her husband, 52-year-old businessman Rande Gerber the morning after a boozy stag do.

The Hollywood star spent his final night as a single man downing tequila shots and vintage red wine with his groomsmen.

Meanwhile, preparations are well underway for the big day, with scaffolding being erected around the main jetty of the Aman Canal Grande Venice, which is hosting the wedding party.

Workers could be seen hauling in vast bouquets of ivory flowers, hinting at the colour scheme the pair have opted for.

A fierce bidding war has broken out among the world's biggest celebrity publications, hoping to capture the moment that the Oscar-winner finally says 'I do'.

It is understood that the US edition of fashion bible Vogue has secured the rights after bidding in excess of £1million.

Any fee given to the couple will be donated to a charity of their choice. The couple have already requested that guests do not bring mobile phones in a bid to prevent unauthorised pictures being leaked from the event.

It's the second marriage for Clooney who wed actress Talia Balsam in 1989 in a service officiated by an Elvis Presley impersonator in Las Vegas.

The actor was previously linked to several beautiful women including Lisa Snowdon and Stacey Kiebler.
