As on of Hollywood’s leading ladies, Jennifer Lawrence prefers not to know her leading men before filming.

The Oscar winner recently explained why it was “actually easier” filming her Die My Love sex scenes with Robert Pattinson than it would have been with an actor she considered a friend beforehand.

“Because Rob and I did not know each other, which is kind of better, you know?” she told Josh Horowitz, according to People. “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.”

Lawrence explained that Die My Love director Lynne Ramsay had them take an interpretive dance lesson before filming a “naked sex tiger” scene on the first day of shooting, in which the two attack each other like jungle cats.

“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,” she recalled.

“And it was like, now blow like a tree — like it was just so embarrassing,” added Lawrence. “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…’

In Die My Love, Lawrence plays young mother Grace, who slowly spirals into madness while locked in an old Montana house, which begins to worry her partner Jackson (Pattinson).
