Hugh Jackman once secretly wet himself on stage during Beauty and the Beast

Appearing on Howard Stern's Sirius XM show this week, Hugh revealed he was suffering with persistent headaches at the time, and sought advice from a naturopath.

The actor revealed: "He said, you're dehydrated. You gotta drink a lot, you gotta drink a lot of water, drink it before five o'clock, like two litres of water.

"So that first day I drank two gallons because I'm like - and you're nuts. You can see what's happening.

"The first song I sing, 'You've been dreaming just one dream', is very, it was so hard to get through. I had to pick her up, I had to drag her around, I had to sing

"As I picked Belle up, a little bit of p*** came out and I'm wearing red tights. And then I thought, uh oh."

The actress playing Belle in the production - which was the original Australian run of the hit musical in 1995 - noticed something was wrong almost immediately.

He added: "Belle's over my shoulder going, 'What's going on?' She's like, 'What's going on?' because I'd stopped singing, I was just marching around."

As the song built to its crescendo, Hugh found himself facing an incredibly difficult decision to make.

He said: "At the end of the song, I had a choice. You sing that F sharp and I either sing it, p*** my pants, or I don't sing it and humiliate myself.

"So I sang it and it was just going, it was just going the whole way. And I immediately, instead of taking my bow, I turned upstage. I just jumped around and I looked down and there was nothing."

Hugh jokingly described his costume as a "wetsuit", with the audience none the wiser about his accident.

He quipped: "I'm like laughing to myself thinking my boot is filled with p***, both boots filled with p***."
