Amanda Seyfried felt "liberated" when filming nude scenes for 'Lovelace'.
The 27-year-old beauty - who plays iconic 1970s adult movie star Linda Lovelace in the new biopic - was comfortable getting naked on camera and didn't undergo a strict exercise regime or diet before filming began.
She told Us Weekly magazine: "I felt liberated. Growing up I was made to think nudity was wrong because it was censored in movies but it was like, 'what's the big deal?'
"I run every day and I try to eat well. Linda was thin but if I stopped eating, I'd just look gross."
Amanda also revealed she and co-star Peter Sarsgaard enjoyed a dinner together to get over any awkwardness before filming their intimate scenes together.
She said: "We had a dinner before filming and we talked about why he decided to do the film. I think his wife, Maggie Gyllenhaal, convinced him to do the role."
Amanda is also no stranger to porn and saw her first blue movie aged just six, although she found it disturbing.
She said: "I was five or six. Six, I think. It was a cop - a guy dressed in a cop costume ... and it was the first time I'd ever seen a penis, and I remember it being very graphic ... it was so terrifying. It was funny. But it was also, like, so, so, so wrong."
