Naked Jennifer Lawrence Was Pelted By A BB Gun While, Of Course, Peeing

"Trust me, you're gonna want to see this 'X-Men.'"

Crotch puncher and professional red carpet klutz Jennifer Lawrence is no stranger to stories involving bodily functions. Just ask her friend Amy Schumer, who recently recounted an incident involving the Oscar winner and a bidet.

Hint: she peed in it. 

In case you were dying for yet another story about Lawrence's bladder, the 25-year-old shared a behind-the-scenes anecdote from the set of her new movie, "X-Men: Apocalypse." During her most recent visit to "The Graham Norton Show," Lawrence described how co-star James McAvoy burst in on her with a BB gun while she was peeing. Hollywood stars, they're just like us?

Apparently, shooting each other with toy weapons is a favorite pastime among X-Men. But during the unfortunate encounter, Lawrence was in the midst of relieving herself, a task made much more difficult by the blue body suit she's required to wear onscreen. 

Although the suit is an improvement on the body makeup Lawrence previously used to become her character, Mystique, it has one fatal flaw: she can't sit down in it. To relieve herself, the actress has to partly remove the suit and use a funnel while standing up. Of course, her cast mates picked this moment to burst in on Lawrence midstream, much to her surprise. 

"It wasn't fair because we were all shooting each other with guns, but you were all in clothes, and I'm naked," she joked. "Trust me, you're gonna want to see this 'X-Men.'"
