Brit babe Keira Knightley has revealed how she had to get drunk to film saucy scenes with co-star Adrien Brody.

The pair were filming thriller The Jacket — and she admitted to downing spirits before the shoot to pluck up some courage.

The 19-year-old was plied with brandy and vodka by Brody. "It helped — but doing those scenes felt completely unreal," she admitted.

"You get one with someone and all of a sudden you're naked and away at it."
