Lake Como was the destination for Emily Blunt and John Krasinski's Italian wedding on Saturday

British actress Emily Blunt and star of the US version of The Office, John Krasinski, exchanged vows on Saturday in a private open air ceremony held at Lake Como in Italy.

Rumour has it the couple spent the week leading up to the big day holed up in George Clooney’s Italian mansion. The groom and Hollywood heartthrob Clooney are said to be friends after working alongside each other on the movie Leatherhead.

Wedding guests, including George Clooney and girlfriend Elisabetta Canalis, were photographed enjoying boat trip up Lake Como before the official ceremony took place.

Sources claim the Young Victoria actress wore a cream Marchesa gown with chiffon, embroidery and a sweetheart neckline for her wedding to Krasinski. The newlyweds were snapped leaving LA airport yesterday after returning home from their secret wedding with the 27-year-old actress sporting an impressive platinum and 3-carat diamond wedding ring.

The pair started dating in 2008 and became engaged last August after the American actor went down on one knee.

Although the couple kept the exact date and location of their wedding tightly under wraps, a US gossip magazine reported that the UK born actress had been spotted dancing the night away in an LA bar surrounded by a gang of girlfriends suggesting she was celebrating her hen do ahead of her impending nuptials.
