Channing Tatum explains how he was sent to the hospital for an injury to his ahem, little Channing while filming his upcoming movie "The Eagle". Also Channing talks about a profession he had before becoming an actor that may shock you.

LOS ANGELES, Calif. -- Channing Tatum and his, ahem, "little man," took one for the team while filming his new movie, "The Eagle," and the sexy action star stopped by Access Hollywood Live to share all of the painful details about his on-set crotch-burning incident!

"It's kind of a painful story," Channing told Access Hollywood Live's Billy Bush and Kit Hoover on Thursday of the wetsuit mishap that sent him to the hospital with a burned personal region. "We were [filming] in a hypothermic river all day, for 13 hours. This poor guy had to run about 15 minutes up the hill to get this water that they're boiling up by the trucks and run it down and then pour it down our wetsuits to keep our core warm so we can stay in the water all day.

"We wrapped the scene, start walking up and here he comes with the bottle," Channing continued. "Normally, he just poured it down -- and it was boiling water -- what happened was he didn't get all the way down to the river to dilute it with river water."

The boiling water "just kept going down" Channing's body, leaving him with a burns down there and earning him a "humiliating" trip to the hospital.

"[I went] straight to the hospital," Channing said. "Which is very, very humiliating holding your little burnt man!"

Kit immediately jumped in to get down to the most important detail, asking, "Little?!?"

"Oh, he was little at that point, I promise you," Channing laughed. "And you have two male nurses like, 'Wow, man, that's really bad,' and you're like, 'Thanks. Can you get me something for this?'"

Billy was horrified to discover that "really hot water" apparently causes the same shrinkage issues as "really cold water."

"[Hot water] does the same thing," Channing informed Billy and Kit. "It [took] an hour to get to the airport."

"One hour till the airport, injured... this guy is a soldier!" Billy laughed.

The scalding couldn't keep the 30-year-old down for long though - Channing said he was back in action in just "one day."

"Back in ACTION action?" Billy prodded, hinting at the star's personal life.

"Four days," Channing revealed, before giving Billy a hearty high-five. "You gotta wrap it up and get back in the game!"
