Shania Twain stopped by The Late Show With James Corden last night (April 18) and shared an amusing anecdote with the host and guests Whitney Cummings and Tyrese Gibson about the time she peed her pants—actually skirt—during a performance in high school.

“When I was a teenager, I got up in front of my peers, you know, a bunch of 16-years-olds in front of the school, and I literally peed myself,” said Shania. “I mean, I was so nervous. So the good thing for me . . . I was quite quick on this. I stood up . . . this was not a little pee, this was a puddle. And when I stood up, it just came out, and thankfully I had a glass of water at my feet, and I knocked it over to hide the puddle—the pee puddle.”

Watch Shania tell the whole story below.
