Jennifer Lawrence prefers filming sex scenes with people she doesn't know.

The Oscar-winning actress has revealed that she actually prefers to shoot X-rated scenes with strangers, rather than friends or long-time colleagues.

During an appearance at 92NY, Jennifer - who recently starred alongside Robert Pattinson in Die My Love - explained: "It was actually easier that way because Rob and I did not know each other, which is kind of better, you know?

"Like in Hunger Games, like me and Josh Hutcherson would have to kiss and that's like … Imagine it.

"You know, it's weirder and so yeah, doing it with a stranger is preferable."

Despite her success, Jennifer finds that acting can still be "very embarrassing".

But Jennifer managed to overcome some of her nerves by taking "interpretive dance lessons" before shooting a scene with Robert.

The 35-year-old star shared: "We got to Calgary like three weeks before we started shooting. Rob and I both [are] embarrassed very easily, and that was mortifying. It was, I mean, I'm not ... a dancer, Rob's [the] worst dancer.

"And, and it was like, now blow like a tree -- like it was just so embarrassing. So I think by the time she was like, 'Yeah, get naked.' We were just kind of like, 'Okay, at least it's not interpretive dance…'"

Meanwhile, Jennifer recently confessed that she doesn't watch her own movies.

The actress is one of the best-paid stars in Hollywood, but Jennifer doesn't enjoy watching herself on the big screen.

Speaking to Leonardo DiCaprio for Variety, Jennifer explained: "No [I don't watch my own films].

"I've never made something like Titanic - if I did, I would watch it.

"Once I was really drunk, I put on American Hustle. I was like, I wonder if I'm good at acting? I put it on, and I don't remember what the answer is."

Jennifer feels she actually learned a lot about acting through working with David O. Russell, the director of Silver Linings Playbook, American Hustle, and Joy.

The actress explained: "He taught me how to act, really.

"I want to be sensitive to the other actors who've worked with him. I know he's tough. He can be really, really hard on people. For me, I don't know if it was because I grew up doing sports, and so I felt like he was just a stern coach. 'Do it loud,' 'Do it quieter,' 'That was b*******,' 'That was bad,' 'Do it better.' He was very straightforward with me.

"I was 21 when I did Silver Linings and it felt alive. I never felt like he was yelling at me. I really don't like being tiptoed around, like I'm an emotional landmine. I hate that."
