George Clooney reportedly took his fiancée, Amal Alamuddin, to the set of "Downton Abbey." The popular British period drama series is currently shooting Season 5 in Surrey.

The newly engaged couple visited "Downton Abbey" set. According to reports, it is one of Alamuddin's favourite shows. She found Clooney's unplanned act romantic.

"George took Amal completely by surprise. He turned up at nearly midnight after jetting into Heathrow," a source said to The Sun, as quoted by Mail Online. "George literally told Amal to grab some clothes before they jumped in a cab down to Surrey."

"She thought it was so romantic, she loves how unpredictable he is. The set visit to Downton Abbey was the icing on the cake of a crazy few hours."

Clooney and Alamuddin, who recently celebrated their engagement at Cafe Habana in Malibu, are expected to get married in September. Mail Online has reported that this profile wedding may take place in Highclere Castle, which is the home of "Downton Abbey" family.

"When he [Clooney] 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. And he was told they would be most happy to accommodate them!"

The source also said that Clooney loves the idea of getting married at the castle, as it is a glamorous place he could secure secure.

The 8th Lord and Lady Carnarvon and their family currently live in Highclere, a residence of the Carnarvon family since 1679. The weddings are allowed and the prices to get parts of the castle alone, begin at about $23,000 for one night, according to Mail Online.
