Channing Tatum named People's Sexiest Man Alive 2012

Channing Tatum rocked the "Magic Mike" stage earlier this year, and now he's been named People magazine's Sexiest Man Alive of 2012.

The 32-year-old actor said he couldn't believe the news.

"My first thought was, 'Y'all are messing with me,'" he said, noting that he immediately told his wife, actress Jenna Dewan-Tatum.

Tatum said, "She was like, 'What?'"

"Yeah, she calls me [the Sexiest Man Alive] now," he added.

Tatum graces the cover of this week's People, which hits newsstands on Friday. In the interview, he opens up about starting a family soon.

"I'm ready; I think she's ready," Tatum said about his wife, whom he married in 2009. "The first number that pops into my head is three, but I just want one to be healthy and then we'll see where we go after that."

Meanwhile, Tatum is currently getting in shape to portray an Olympian in the upcoming film, "Foxcatcher."

"I like to be lean," said Tatum, who weighs 195 pounds. "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."

Tatum's movie credits include "Step Up," "21 Jump Street," "The Vow" and "G.I. Joe: The Rise of Cobra."

And his film career is just heating up. The former dancer/model will also star in "G.I. Joe: Retaliation," "White House Down" and "21 Jump Street 2," among other films.
