Channing Tatum "burned the skin off" his penis.

The 29-year-old actor suffered the agonising injury while trying to keep warm when shooting 'The Eagle of the Ninth' in the Scottish Highlands in October.

He explained: "The only way to keep warm was by pouring a mix of boiling water and river water down your suit. We were finally done shooting for the day, and one of the crew guys asks if I want to warm up before I go. I'm like, Nah, I'm good. And then I thought, Why not?

"Thing is, he'd forgotten to dilute the kettle water. So he poured scalding water down my suit. And I was trying to pull the suit away from my body to somehow get away from the boiling water, and the more I pulled the suit away, the lower the water went. It just went straight down and pretty much burned the skin off the head of my d**k."

Channing  - who describes the incident as "the most painful thing" he had ever experienced - was taken to hospital, but with the nearest medical facility over an hour away, the former stripper struggled to cope with the agony.

He added to Details magazine: "I said to the driver, who was ex-special-forces Marines, 'You might have to knock me out, because I don't know if I can take the pain. Just grab something and hit me on the back of my head.

"I had five guys looking at my shrivelled, burned penis."

Fortunately, the actor - who is married to actress Jenna Dewan - made a full recovery.

He added: "I'm good . . . now.  My penis is fantastic! 100 per cent recovered. Put me back in the game, Coach."
