Ah, they grow up so fast!
But as the hunky actor reminded us all during his appearance on Friday's Ellen, it's already been "six months" since he became a father.
"She just got her first tooth," Tatum told Ellen DeGeneres via satellite. "It's the cutest thing. Razor sharp. I think she's going to be cutting me very soon, but it's as cute as can be."
The 33-year-old star couldn't be there in person to chat with DeGeneres as he is currently shooting the sequel to 21 Jump Street in New Orleans with Jonah Hill, conveniently called 22 Jump Street.
"We got really creative on that one," the actor quipped regarding the title.
Speaking of sequels, will there be one to Tatum's hit stripper flick Magic Mike?
"Yup. For sure," Tatum revealed, much to the delight of the studio audience. "I'm going to start writing it with my producing partner...We're going to start writing that this year probably and probably start filming it about this time next year."
