Carey Mulligan stopped by cops after Red Bull binge

Carey Mulligan was once pulled over by police for "veering around in the road" while driving in Los Angeles - because she was "so wired" after bingeing on an energy drink.

The An Education star had a brush with the law when she was taking her Drive director Nicolas Winding Refn home, but the cop who pulled them over decided not to take further action.

She tells New York Magazine blog Vulture, "We almost got arrested once in L.A. I used to drive him to and from work when we were doing the movie... and one day we shot until two in the morning.

"I'd never had Red Bull before, and I had, like, six of them that night, and I was like, 'This is the best thing, ever!' So I was freaking out. We got in the car at the end of the night, and I had been wearing these shoes that really hurt, and I had pink fluffy slippers in the back of my car and I put them on...

"So we got in my white Prius and we were driving out of downtown Los Angeles... and I was trying to do the navigational thing while he was sitting next to me - he cannot drive, he's made a film about driving, but he cannot drive - and I'm so wired on Red Bull that I think my head's going to burst, so I'm, like, veering around in the road.

"There's no one around, it's two in the morning, but suddenly there are flashing lights and I get pulled over. The policeman comes round and I roll down the window and he tells me that I was weaving - which I was, since I was trying to figure out my nav guide - and I'm sitting there in my pink fluffy slippers, Nic's sitting there in his Puma tracksuit looking like a drug addict, and the policeman's like, 'What are you doing?' And I say, 'I'm not drunk I just had 17 Red Bulls!' And Nic's like, 'We're making a movie.'

"It was so uncomfortable, and the cop just looked at us like, we're making a movie, really? We looked ridiculous. Thank God he didn't want to do the paperwork and he let us go."
