Another day, another quirky JLaw anecdote, right?

If she isn't 'scratching her butt' on sacred Hawaiian stones, she's urinating in secret beside her mum, and then sharing the photographic evidence with the world.

So, while appearing on The Late Late Show with James Corden this week, the Oscar-winner gave a little background into what looks like a candid mother/daughter snap.

"I am actually peeing in that photo and she has no idea. No clue," Jennifer told James in footage which has racked up more than 12,000 views on YouTube.

"I went to pee and my friend got the phone cos she knew I was peeing, and we both decided to leave my mom out of it," Jennifer explained.

Complimenting the Passengers actress on her pose, James remarked: "That's a very relaxed peeing face" to which Jlaw replied: "Yeah, I know how to do it. I've done it alot."

Commenting on the upload, one YouTuber wrote: "I like her, but a peeing story is really not cute at all."

"Do people still think this disgusting, vulgar behavior is cute?" added another.

Well, that went well.
