Actress Keira Knightley, who has worked with Benedict Cumberbatch in "The Imitation Game", feels "terrified" with the female fans of the actor.

The British actress was talking about her new movie on "Late Night with Seth Meyers", when she spoke about Cumberbatch's female fans, who have been dubbed as "The Cumberbitches", reports mirror.co.uk.

"The Cumberbitches, it's terrifying. I mean, they're lovely. I feel terrified saying they're terrifying cause they might come after me. So... yes, it's amazing. They're very artistic. They paint pictures of him.

`You go to premieres and there's these amazing paintings of Ben looking Ben-like... (They're) a very hysterical, artistic type,` she said.

During her interview, the 29-year-old says how she was actually snubbed by the 'Cumberbitches' over an autograph as all they wanted was the `Sherlock` star.

`I actually had a really embarrassing moment at the London premiere, because, they really do, they scream more than I've ever heard for anyone else, but I had a publicist with me and she went, 'You know, go sign some autographs'.

`I went over there and went, 'Oh yeah, of course, of course, no problem!' And they were like, 'Oh no, we don't want you. We're just here for Ben',` Knightley said recalling the incident at the premiere of `The Imitation Game`.
