Jennifer Lawrence sat down for an interview with Howard Stern back in February, but video from their chat is only now being released, and it’s a doozy.

In the interview with SiriusXM’s “The Howard Stern Show”, the “Red Sparrow” star recalled attending Ellen DeGeneres’ birthday party and dealing with the consequences when she decided to take a puff on a joint offered to her by a rapper.

“I was done and went to go see my ride, and my ride wasn’t ready to leave yet,” she explained to Stern. “So, I smoked a joint with some rappers.”

It didn’t take long before Lawrence, 28, discovered that “their s**t is different. So I entered a different universe.”

The weed caused her to become so high, she revealed, that it led to a hilariously weird altercation outside a porta-pottie.

“So, I went to the porta pot to go pee. There was a woman there, who was like, ‘No, no, no, go ahead!’ I was like, ‘You were here first. You go!’ And she was like, ‘No, go!'” she continued.

“I’m in the porta pot and I was like, ‘She’s gotta poop. This poor woman’s just gotta poop.’ So I came out and went up to her, was like, ‘Look, you gotta poop.’ And she was like, ‘No, I don’t. I don’t know why you’re saying that,'” added Lawrence.

“All of a sudden, security is grabbing me because I hadn’t realized I am grabbing this woman by the shoulders, shaking her, screaming, ‘You have to poop! You have to poop!'” she said. “Security is laughing so hard because he’s heard the whole exchange. He’s like, ‘You can’t grab her. But, I agree. She’s gotta poop.'”

Ultimately, revealed Lawrence, “The woman finally just started laughing. I was like, ‘Just… poop…'”

Meanwhile, another party attendee backed up Lawrence’s claims, with David Spade telling DeGeneres that he apparently took a hit from the same joint after seeing JLaw hanging out with rapper French Montana.

“I take the biggest hit,” Spade recalled. “And I cough maybe 40 minutes.” Watch:
