Channing Tatum's Baby-To-Be Has Him Nervous: 'I Hope I Don't Screw That One Up'

Channing Tatum may have had one of the most successful years of his career in 2012, but the actor thinks 2013 is going to be even better.

Why, you may ask? The "Side Effects" star is going to be a daddy. (One hunky daddy, might we add).

"That [will] be the biggest role of my life. I hope I don’t screw that one up,” Tatum told reporters of impending fatherhood.

The 32-year-old and his wife Jenna Dewan-Tatum, also 32, are expecting their first child this summer, and are slowly gearing up for parenthood. Tatum recently revealed to E! News how scared (and excited) he is to become a dad.

"I don't think there's one thing that doesn't terrify you, but in the most unbelievably beautiful way," he gushed. "Someone said it's really like watching your heart jump out of your body and run around, and I think that can possibly be the coolest thing that I've heard of."

Another thing that has Tatum all riled up? His wife's new "animalistic" take on life!

"I mean, women just sort of turn into like animals in this sort of stage that they're in," Tatum said of pregnancy, joking that Jenna is "a complete animal right now!"

"You can ask her, but in the most beautiful like humanistic animal-y way," he added, "You know she works out all of the time, eats right, impeccably right. She's just a machine."

Speaking of machines, Tatum confessed he's taking a nice break from Hollywood.

“I hope to slow to down a little bit when the little person comes into the world,” he noted.
