Jennifer Lawrence has revealed that she had to get “really, really drunk” in order to marshal her nerves ahead of filming a sex scene with fellow Hollywood A-lister Chris Pratt, because he’s a married man. She explained that the scene, for their upcoming movie Passengers, is the “most vulnerable I’ve ever been.”

“I got really, really drunk,” she revealed in a new feature with The Hollywood Reporter, but that didn’t end up solving the problem. “That led to more anxiety when I got home because I was like, ‘What have I done? I don't know’.”

36 year old Pratt, who became one of the hottest properties in Hollywood last year, is married to actress Anna Faris. It was the first time that Lawrence has ever filmed a nude scene with a married man, and said that the tension between providing realism and not violating the sanctity of a marriage made her feel enormous pressure.

"He was married... and it was going to be my first time kissing a married man, and guilt is the worst feeling in your stomach. And I knew it was my job, but I couldn't tell my stomach that. So I called my mom, and I was like, ‘Will you just tell me it's OK?’”

Sci-fi-based movie Passengers, directed by Morten Tyldum, is set to be released in December 2016, and sees Pratt and Lawrence fall in love while piloting a spacecraft to a distant colony.

Lawrence was speaking during a special Actress Roundtable feature alongside other prominent female actors, such as Carey Mulligan, Cate Blanchett and Jane Fonda. Mulligan, current star of Suffragette, also revealed that she gets nervous filming nude scenes but has found a way to combat that.

“There's always the things that you think are going to be tough,” she said. “I've been nude once, and I was like, “Oh, that's going to be a nightmare,” and actually that was fine. “It's kind of, ‘f*** it, now I'm naked and everyone else isn't. This is hilarious.”
