Call him the Sexiest Dad Alive.

Channing Tatum has been on baby duty, caring for four-month old daughter Everly, while his wife Jenna Dewan-Tatum is on the set of her new TV show "Witches of East End."

"He is getting really good at being the set husband - that's what I call him," Dewan-Tatum, 32, told " ET Canada."

"He's in the trailer, he's rocking her to sleep, I'm running back and forth breastfeeding," Dewan-Tatum said about the man once named People magazine's Sexiest Man Alive.

"He's been amazing - every chance he gets he's here. He's like, 'I could sit here and be set husband all day long. This is so fun!'"

The first-time parents welcomed Everly in May. A few months later in July, Dewan-Tatum reported to the Vancouver set of her new show, which premieres Oct. 10 on Lifetime.

"We knew it was coming," Dewan-Tatum told "ET Canada." "I knew I had this show coming up, and we just knew, okay, let's get through these four months and prepare for it as much as possible, which I'm learning is the key of motherhood: prepping. It's going good so far."
