“I’m ready [to start a family]; I think she’s ready,” says Tatum, 32, who married actress Jenna Dewan-Tatum 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.”
Admitting he loves to give massages, Tatum sounds like a sensitive hubby.
“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!'”
When he first heard of his “sexy” title, he thought it was a joke. “My first thought was, ‘Y’all are messing with me,'” the hunk says. “I told Jenna after we’d been in the bathtub washing our dogs because they’d gotten skunked.”
He adds,”She was like, ‘What?'”
And it’s become an ongoing joke in the Dewan-Tatum household.
“Yeah, she calls me [the Sexiest Man Alive] now,” he laughs.
Currently training to play an Olympic athlete in the upcoming flick Foxcatcher, Tatum is lean and ripped 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.”
And his Step Up star wife says there’s much more to her sexy hubby than a pretty face.
“People know him to be fun and sexy, but they don’t know how emotionally deep and spiritually open he is,” shares Dewan-Tatum, 31. “He is such an open-hearted person; what you see is what you get.”
