Downton Abbey's Allen Leech has revealed George Clooney caused chaos when he made an appearance on the set of the period drama.
The Hollywood star filmed a cameo on the ITV show in September for a sketch which will air as part of charity appeal Text Santa in December.
Allen, who plays chauffeur turned estate-manager Tom Branson, joked to E! News: "I'll put it this way: I've never seen so many female crew members arrive and be on set when they weren't actually supposed to be. It was very interesting."
He added: "He had to work very hard. I've never seen someone being chased by so many paparazzi leaving the set of Downton Abbey!"
But it seems the girls weren't the only ones going gooey for Clooney - even Allen was besotted after working with him.
The Irish actor continues: "He was such a lovely man. So intelligent, so articulate as well about not only acting but also world affairs.
"A great man, and a brilliant actor and a brilliant director and it was just so much fun and he had a blast."
"It was great. And I don't want to spoil it but it's very very funny, I've seen it and the interactions that George has with everyone in the cast are hilarious, so I think everyone will enjoy it and it will be a real treat and it was great of him to come in and do something like that for us."
