AT A GLANCE
• Channing Tatum named 2012's Sexiest Man Alive by PEOPLE magazine
• The modest actor said, "My first thought was, 'Y'all are messing with me'"
• Tatum added his wife Jenna Dewan-Tatum, "calls me [the Sexiest Man Alive] now"
He may have bared (almost) all of that incredibly chiseled body in
"My first thought was, 'Y'all are messing with me,'" says Tatum, who . "I told Jenna after we'd been in the bathtub washing our dogs because they'd gotten skunked."
Says the actor: "She was like, 'What?'"
"Yeah, she calls me [the Sexiest Man Alive] now," he adds. And who can blame her?
"It’s really easy for us guys to say, 'I want like 15 kids,'" he continues. "Jenna will be like, 'Well you better get another wife!'"
Currently training to play an Olympic athlete in next year's Foxcatcher, Tatum is all heart and muscle at 195 pounds. "I like to be lean. If I get too bulky I can't move well and I like to move," he says. "When I'm not training, I get really round and soft."
Which is just fine by his wife. "People know him to be fun and sexy, but they don't know how emotionally deep and spiritually open he is," says , 31. "He is such an open-hearted person; what you see is what you get."
