The Hollywood couple welcomed Everly into the world on 31 May in a London hospital and the first time parents worked out early on how to soothe the tot.
Speaking on Ellen DeGeneres' chat show, 32-year-old Jenna said: "The baby is crying and you're like, 'What do I do to make her stop crying?'
"And all of a sudden, he starts beatboxing and she starts cooing. I'm like, what? I have been rocking her. I have been swaying her. I've been doing squats and he gets here and he beatboxes."
Jenna, who is starring in new drama Witches of East End - her first acting role since giving birth, continued to say that Channing was an "amazing" dad, adding that four-month-old Everly now just "falls asleep in his arms". Aww!
It seems like Magic Mike actor Channing has thrown himself into fatherhood. The 33-year-old even previously admitted to being a pro at changing nappies!
Gushing about her husband, Jenna continued: "It's funny - he's so sensitive. He's like this really strong big guy in life, but you give him this little baby and he's like, 'Oh my god, is she going to drop? Am I doing everything ok?'"
