The 'White House Down' actor also opens up about secret to his happy marriage to Jenna Dewan and the R-rated dolls his friends send him.
Channing Tatum tells Cosmopolitan something about him that not many people knew. Mr. July "Cosmo Guy", who was dubbed PEOPLE's Sexiest Man Alive in 2012, says he would be crossed out of the sexy list if people knew that he was "a fat kid on the inside" who often used his exercise as an excuse to eat more pizza and burgers.
"I love food so much, and I fluctuate about 25 to 30 pounds between movies," he reasons. "I feel like I have to do a chess movie that requires very little movement at some point, just so I can eat pizza and play chess on the beach all day. And then eat more pizza and cheese-burgers and drink beer. That'd be amazing. I'd give anything for that. I gotta figure that movie out."
He also talks about secret to his happy marriage to Jenna Dewan, who is currently pregnant with their first child. "You have to want it. Jenna's and my thing is checking in with each other all the time, like 'On a scale from 1 to 10, how much do you love me right now?' And you gotta be honest, and you've got to want an honest answer," he shares.
Of what keeps him grounded, he says it's his friends. "It's embarrassing to tell you how much my friends make fun of me. Seriously, when you have a doll made of your face, it's ridiculous how creative your friends can get...pictures, videos, little animated cartoons that they've made. And they're way, way not PG-13. So I get chopped down to size all the time," he dishes on.
The "White House Down" actor, who has been staying in London with his wife for the past few months while waiting for the arrival of their baby, additionally reveals his admiration towards fellow star, Oscar-winning actress Jennifer Lawrence. "I wouldn't mind being the male Jennifer Lawrence. I think she's incredibly cool," he says.
