Jennifer Lawrence has revealed a crazy injury she got while filming upcoming new horror flick Mother!

The star admitted she felt "severely miscast" when she began shooting for her beau Darren Aronofsky's film, in which she was cast alongside Michelle Pfeiffer, Kristen Wiig and Domhnall Gleeson, the Daily Mail reports.

She confessed: "That's what scared me and I thought I was severely miscast. I found time to find who she was while working with Darren and I was able to pull out this personality that I didn't know existed."

And once she found the role within her, Jennifer went so deep into it she hyperventilated excessively to the point of a serious injury for a dramatic scene.


"I tore my diaphragm for hyperventilating. People thought I was beaten up so want to clear it up that I did it to myself. It was my own doing," she hilariously admitted.

The movie had been written and directed by Aronofsky, who is now dating Jennifer, with the glamorous couple embarking on a relationship privately in September 2016 after filming for Mother! had wrapped.

Meanwhile, Darren also proved to be unsure about casting Jennifer in the role, revealing at the premiere: "It was so interesting because people talked about how great, talented and gifted she was. I had never seen her do anything like this before and I didn't know if she would or could do it.

"She taught herself to act and she is a very technical actor. She just absorbed all the material we gave her and unleashed it and it exploded," he concluded.
