"I've got to probably stop doing stupid stuff," a resigned Channing tells ET's Rocsi Diaz while discussing the urge to take on some of the crazier stunts in the movie, adding of fatherhood, "It feels amazing. I can't really put it into words."

Channing and wife Jenna Dewan-Tatum had their baby girl, Everly, on May 31 of this year, and Jamie's already got two girls. So what's going to happen when Channing's little angel starts dating?

"I can't really say anything because I have a lot of things I have to explain to her," says Channing with a grin. "She's going to be like, 'Daddy, what were you doing before this?' And, 'What's Magic Mike?' I've got a lot of things that I'm in for."

"When that time comes, you have to speak to them like the father," says Jamie about having his daughters date boys and handling troubling situations. "I think if you are able to sort of step away from the old school parenting and be a little more chill, especially with your daughters, it all works out – and then go with the flow."
