Looks like Hugh Jackman can give Gerard Depardieu a run for his money!

Depardieu may have urinated on a plane, but Real Steel's Jackman has him beat: He once relieved himself on stage, in front of a theater audience.

"The first show I ever did, singing and dancing, was Beauty and the Beast. I was playing Gaston," Jackman, 42, tells Rachael Ray in an interview airing Friday. "Gaston has red tights, knee high boots, and it's very physical. I had headaches everyday for two months. I went to an astropath [psychic] and he said 'Well, you're dehydrated.' So of course [following his advice] I had four liters of water," says Jackman of his 1996 theater days in Melbourne, Australia.

"I go down to the stage, getting ready for my first number…and I'm like I really need to go again. [The routine is] the most cardiovascular song I've ever done: literally I'm picking up Belle and as I pick her up, I stopped singing and right in that moment I realized the muscles you need to release in order to sing are the ones you do not want to release if you need to go," the actor tells Ray.

Urinating on stage in front of the audience, Jackman says he had to forgo the number in order to relieve himself.

"I'm carrying her [over one shoulder] not singing, and she's going 'What's going on? What's going on?' So finally, it's embarrassing at this point," he tells Ray. "I've not sung an entire verse."
