Jennifer Lawrence might have shared a bit too much information in a recent interview with KISS FM.

The Joy star revealed a (very) behind-the-scenes tidbit about close friend and Silver Linings Playbook co-star Bradley Cooper.

“When we were doing our dance lessons together, I’m pretty sure he sweats from his butt first,” she brazenly revealed. “You know, you’ve got pit stains everywhere but like his butt would start sweating and I’m like, “Is your butt sweating before your armpits are sweating?'”

The actress, however, never discussed the sticky issue with Cooper in the hopes of keeping their “sexual chemistry” alive. “We didn’t, you know, have long conversations about it. It’s just something I kind of like clocked’. 

This month, Lawrence and her “sweaty butt”; co-star reunite for the fourth time on-screen in the Christmas day drama Joy.
