Michelle Dockery Has Got An American Alias

Playing a lead character in Downton Abbey comes with a downside - unwanted attention from fans who are keen to meet their favourite television characters in person.

So who can blame Michelle Dockery, who plays Lady Mary Crawley in the ITV series, for coming up with a clever solution to this problem.

In an interview with the Radio Times, the 32-year-old actress revealed she has developed an American alter-ego who just so happens to resemble her famous character.

Her alias? Britney from Beverly Hills.

"It's a silly spoof, but it passes the time," she explained to the magazine. "We're always sending ourselves up. Even on set, when you're doing a serious scene, you can't help but see the funny version."

Unfortunately Dockery doesn't share any more details about 'Britney,' but she does expand on how she copes with her Downton fame.

"Sometimes they want selfies, and I've said no occasionally, although you don't have to be rude.

"There's a time and place. If I'm with my godchildren having a meal in a restaurant and someone wants a picture, which I realise might make their day, it's not appropriate."

Dockery also notices a difference between her fans in Britain and in the US.

"Generally in London no one even looks because they're going their own way, but in Los Angeles people expect to see someone off TV or in a film walking the dog, so you're approached more," she says.

However, Michelle isn't complaining about landing the Lady Mary role. She adds, "There aren't many disadvantages to being in a show like this."
