George Clooney is planning to marry in Venice.

The 'Monuments Men' actor and human rights lawyer Amal Alamuddin - who got engaged in April - are to tie the knot in Italy in September and decided against holding their wedding at his Lake Como estate because they felt it wasn't private enough.

A source told the New York Post newspaper's Page Six column: ''George and Amal want to be married in Italy, but they need a location that offers them and their guests privacy.''

George - who also didn't want to inconvenience his Lake Como neighbours with the attention his wedding would bring - and Amal were seen dining in Venice a few weeks ago after touring wedding venues and are said to be planning to marry at a palace in the city.

The pair visited Venetian restaurant Da Ivo along with the 53-year-old actor's bodyguard and his girlfriend, and they enjoyed a feast of sautéed shellfish, smoked tuna, mussel soup, crayfish and artichoke risotto and charcoal-grilled seabass accompanied by Prosecco and white wine.

The next morning, they flew out of Venice airport by helicopter.

It was recently claimed the couple had been considering marrying at Highclere Castle - the Hampshire estate where 'Downton Abbey' is filmed - but had a change of heart after Amal learned British ex-glamour model Katie Price had tied the knot there with first husband Peter Andre in 2005.

A source said: ''Amal doesn't really know that much about celebrity.

''But she is well aware who Katie Price is and didn't want her big day to be in any way associated with that kind of media circus.

''So they've gone back to the drawing board and are looking at other places.''
