While promoting upcoming Alan Turing biopic The Imitation Game, Keira Knightley told Variety that she was called “disgusting” for bringing a girl to her school prom.

According PinkNews, Knightley told Variety that she “went to prom with [her] best mate, Emily” and was discriminated against by teachers.

She explained, “We both turned up an hour late, and I’d been filming Bend It Like Beckham, and I turned up in leather pants and a crop top. She was a model for a while, and she’d been in Paris shooting something, and she turned up as the boy. She had a black tie with ripped jeans on, and everybody else was completely dressed up, obviously, in that kind of finery.

“One of the teachers took us both aside and said we were never going to come to anything if we didn’t know how to dress appropriately for events like that. So that was my prom. We had a great time!”

“We had our picture taken underneath the thing, and she’s kissing me, and we were told that that was ‘disgusting’.

“Our photograph, though, wasn’t allowed – you know when you get up and, I don’t know if this is in America, but you collect all the photographs of prom and you buy whatever ones you want.

“Ours wasn’t allowed to be displayed on that because it wasn’t appropriate.”

The Imitation Game, starring Knightley and Benedict Cumberbatch is released in Ireland on November 14.
