Gemma Arterton and Mackenzie Crook were so nervous about filming sex scenes together for their new movie THREE AND OUT, they chain-smoked throughout the shoot to calm their anxieties.
The 22-year-old actress admits she turned to nicotine to help her get through the harrowing experience.
She says, "It was petrifying. I think it's one of the hardest things I've ever done. It was my first love scene so it was terrifying.
"We both got through it by smoking away in between each take."
And the star - who is completely topless in one bedroom scene - is happy for her parents to watch the film, although she won't be sitting down with them.
She says, "I don't mind my parents watching it. It's awkward but they're OK with these things."
