But there’s one thing he’s still lacking: mastering the art of diapering.
“I have never changed a diaper before, so I may need some help learning,” Tatum, 32, tells PEOPLE at Thursday’s New York premiere of his new movie Side Effects, presented by the Cinema Society and Michael Kors.
“I don’t have friends who have kids, so it’s going to be an interesting experience to learn how to change a diaper. I hope I don’t have any problems where the diaper falls off and the baby poops on the ground,” says PEOPLE’s Sexiest Man Alive, whose baby with wife Jenna Dewan-Tatum, 32, is due this summer.
“But once the baby is born, I’ll definitely do the diaper changing. If it means touching the poop and getting peed on, I’ll still do it. I’m up for the challenge.”
“Oh man, I’m not even getting into what I do to pamper Jenna. I’m doing anything that she asks for,” he explains. “She jokes to me all the time by saying, ‘If I feel good, then the baby feels good’ or ‘If I’m happy, then the baby is happy.’ And I’m like, ‘That is such an urban myth. You’re just saying that to get me to do everything for you.'”
“I know it’s probably true, but I like to joke about it and she hates it. I’ll go to the store to pick up shakes or give her 1000 foot rubs. A foot rub now through the nine months if I have to, just to keep her happy and comfortable.”
