Keira Knightley seems to have it all together and while some celebrities gain attention by getting drunk, naked or arrested in public, you aren’t likely to catch Keira stumbling out of a club or on the highway getting a breathalizer test.

Although Keira might not be very rebellious these days, she recently talked about her younger days and implied that she was a bit of a rebel as a teenager.

Keira recently described her prom night to Vulture.com and said that her date was actually another girl.

She said the two of them surprised everyone by attending prom together and angered many of the teachers and parents, who told them they were being inappropriate.

She said the adults and staff at the prom were also upset when the girls posed together for a prom picture and kissed.

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

The school also refused to display the prom photos with the others.

“Our photograph wasn’t allowed – you know when you get up and 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,” she added.

Keira went on to say that the school wasn’t happy with what the two girls were wearing either.

“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, and she was a model for a while, and she’d been in Paris shooting something, and she turned up as the boy, so 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!”

Keira has clearly made something of herself and while her rebellious days may be behind her, it’s nice she can look back on them and laugh.
