That's one way to get closer with your co-star!

Tom Hiddleston appeared on Thursday's Graham Norton Show, where he opened up about the time he... um.. peed on his Night Manager co-star over a jellyfish sting.

"Tom got stung by a jellyfish and he shouted across the beach, 'I say old sport could you come and pee on me?' And I engagingly obliged," the 36-year-old actor shared, confirming the story.

However, Hiddleston later learned that his noble -- gross -- effort may have all been for naught.

"I’ve since read up on it and I don’t think it works," he explained. "It’s an old wives’ tale."

Well... sometimes it's the thought that counts.
