Ed Westwick drunkenly "skied" to a bar while working on his new movie.

The actor and his 'Chalet Girl' co-stars were left bemused as to how to move to another drinking establishment in St. Anton - the Austrian ski resort where the film was shot - but came up with a novel way on how to tackle the slopes.

Tamsin Eggerton, who also appears in the movie, explained: "We went to the Krazy Kangaroo bar and we had a few Jaegermeisters too many and we didn't know how to get down the slope to the next bar. So Ed just got on his back and 'skied' all the way down and everyone was like, 'Ooh!' and then the other guys said, 'That's really cool, I want to do that.'

"I just turned to the other girls and said, 'I don't think this is a good idea' and then just slipped and fell. They were like 'Oh no!', but then they had to do it too so we all just kind of piled out, fell on top of each other at the end and then went back into the bar. We just brushed ourselves off and went back into the bar. It was very odd."

Tamsin was relieved to escape serious injury following her drunken escapade, and is certain the film's bosses would not be happy if they knew what had happened.

Speaking on the red carpet at the world premiere of the movie at London's Vue Westfield this evening (08.02.11), she told BANG Showbiz: "No serious injuries, thank God. I had a friend who did that and really shattered her shoulder. I don't think the insurance would cover that."

Joining Tamsin on the red carpet at the premiere were co-stars Ed, Bill Bailey and Felicity Jones.

'Chalet Girl' - which also stars Sophia Bush - opens in the UK on March 15.
