Jennifer Lawrence’s 2018 was full of hysterical moments – including a pot-induced party mishap that left her and a stranger rolling “on the ground laughing.”

SiriusXM’s “The Howard Stern Show” recently shared a throwback clip of the “Mother!” actress recounting one of her wilder incidents of the year, which took place at Ellen DeGeneres’ 60th birthday bash back in January.

In the clip, Jen said that she was down to head home after a fun evening at Ellen’s, but the friend that gave her a ride to the party wasn’t ready to call it a night just yet. To pass the time, the Oscar winner ended up kicking back with some particularly potent weed.

“[I] smoked a joint with some rappers,” she explained. “And their s*** is different. So, I entered a different universe.”

Jennifer eventually wandered off to use a portable toilet, but she wasn’t the only person in line.

“There was a woman there, and she was like, ‘No no, go on, go ahead,’” she remembered. “And I was like, ‘No no no, you were here first.’”

After going back and forth for a while, the “Red Sparrow” star eventually acquiesced and went in – but she came to a revelation while inside.

“I’m in the porta pot, and I’m like, ‘She’s gotta poop!’ You know, this poor woman’s just gotta poop!” she said. “So, I came out and made a beeline for her, and I came up to her. And I was like, ‘Look, you gotta poop.’”

While Jennifer thought she was being considerate, reality came crashing in when a security guard abruptly pulled her away.

“What I hadn’t realized is: I’m grabbing this woman by the shoulders, shaking her, screaming, ‘You have to poop! You have to poop!’” she explained.

Despite her accidental bout of hysteria, Jen wasn’t kicked out of the party. In fact, the security guard who broke up the brawl agreed with her quest.

“[He’s] laughing so hard, because he’s heard the whole exchange,” she recalled. “He’s like, ‘You can’t grab her, but I agree! She’s gotta poop!’ And she and I were just on the ground laughing.”

“So you were so high that you acted inappropriately?” Howard asked.

“Yes,” she laughed.

While Jen may have gone too hard at Ellen’s bash, she wasn’t the only one.

Back in February, David Spade told the talk show host he got so high at her big 6-0 that he coughed for “maybe 40 minutes,” mistook her for Justin Bieber and forgot how he got home.
