Go ahead and delete another state capital from your brain—there's a new, crucial piece of information about Bradley Cooper's butt to be remembered, brought to you by your friendly neighborhood celebrity Jennifer Lawrence.

"When we were doing our dance lessons together, I'm pretty sure he sweats from his butt first," she said in an interview with KISS FM. "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?'"

They didn't talk about Brad's overactive-gland problem (I hear Botox helps) to maintain their "sexual chemistry" on set, but true to form, JLaw made a study of his condition ("It's just something I kind of like clocked"), then presented her findings on a nationally syndicated radio show years later while promoting their latest film.
