Jennifer Lawrence has recovered gracefully from a stumble on her way onstage to receive an Oscar, fought publicly against the Hollywood wage gap, and fired many, many arrows into the idea that women can’t lead franchise movies. So what can possibly scare Jennifer Lawrence? A sex scene, believe it or not.

Speaking as part of the always fascinating Hollywood Reporter actress roundtable, Lawrence opened up about her work in the upcoming Passengers, a space-set romance in which she stars opposite Chris Pratt: “I had my first real sex scene a couple weeks ago, and it was really bizarre. It was really weird.”

Not that anything went wrong on the set—according to Lawrence, everyone was perfectly professional, which from what we hear is basically the only way to survive filming a sex scene. But for all the time she’s spent kissing both Liam Hemsworth and Josh Hutcherson in the Hunger Games films, a sex scene in Passengers was a major shift—especially because Pratt is married. “It was going to be my first time kissing a married man, and guilt is the worst feeling in your stomach,” Lawrence explained. “And I knew it was my job, but I couldn’t tell my stomach that.”

She even called her mom to tell her it was O.K. to film the scene, and even afterwards the discomfort didn’t end: “You want to do it real, you want everything to be real, but then . . . That was the most vulnerable I’ve ever been.”

So for those of you needing more evidence that Lawrence, more than maybe any other star, is Just Like Us, look no further: in the same way any of us would panic and run away when asked to do a sex scene with a married near-stranger, Lawrence didn’t take the duty any more lightly. But she’s also not at all like us, because she‘s an actual professional: you know not an ounce of that anxiety will show on-screen.

Other highlights of the T.H.R. roundtable, which is always worth a read: Lawrence saying she would be a nurse if she weren’t an actress, Helen Mirren admitting that acting only gets scarier as you get older, and Cate Blanchett talking about the moment in week three of making a play where “you fucking lose it and everything falls apart.”
