George Clooney may wed Amal Alamuddin at Highclere Castle, the country house where 'Downton Abbey' is filmed, according to reports.

The 'Oceans Eleven' star whisked his fiancee Amal Alamuddin away for a romantic break in the English countryside this week, which took in Highclere Castle near London - where the period drama is filmed - and she was so taken by it, they made enquiries as to whether it could be used for their wedding.

A source told a UK publication that Clooney became close friends with Hugh Bonneville, who plays Lord Robert Crawley, when they did 'The Monuments Men' together last year, Contactmusic reported.

They really hit it off, and Clooney contacted Bonneville and asked him to arrange a private tour of the castle. Amal was blown away, the source said.

The insider added that when he saw his bride-to-be's reaction to the spectacular Victorian castle, set on 1,000 acres of parkland, he began making some discrete inquires about having their wedding performed there.

Highclere is thought to be a good venue for the wedding as it is close to London and also to Heathrow airport, meaning George's family from America can easily fly, as can Amal's extended family who live in Dubai and Lebanon.
