Jennifer Lawrence has always shown plenty of irreverence when it comes to her fellow Hollywood sweethearts. Or did you forget the 2014 facepalming of Emma Watson? But Lawrence gently shoving Hermione Granger in the face is nothing compared to what she did to Game of Thrones star Sophie Turner on the set of X-Men: Apocalypse.

Turner has grown up in front of our eyes for six seasons as the once-innocent Sansa Stark on Game of Thrones. So it can be easy to forget the actress is already 20 years old. But that knowledge makes this story of Jennifer Lawrence literally punching below the belt a bit easier to digest. Speaking with the site Just Jared, Turner explained how J.Law treated her as if she were just one of the boys while filming X-Men: Apocalypse:

She is just how you’d want Jennifer Lawrence to be. She’s exactly the same person that you see in interviews. And she was just amazing. She was really fun, really cool. She punched me in the vagina once. I didn’t ask her to either. It just happened. Evan [Peters] and I were having a fake fight and I said something like, “I’ll c-nt punch you” or “I’ll punch you in the crotch” and then Jen thought that I said, ”Please c-nt punch me Jen.” So she punched me in the vagina and I was like, “Awesome.” It was pretty funny.
