This is The Rock's second daughter, and his first child with long-time girlfriend Lauren Hashian.
"Both Mom and Dad are over the moon. Christmas definitely came early!" a source told the publication.

Earlier this week the new mom posted a photo of the couple on Instagram, with a caption suggesting she is a little bit afraid of just how large a baby who is half The Rock might be:
"So grateful and in awe of this time. To experience creating a little life is just incredible. This beautiful cycle of life and womanhood beginning again. And like Big Daddy says - Couldn't be prouder of all the kickass women she's going to have around her! And Men of course ;).. #LetsJustHopeBigDaddyDoesnt=20lbBaby."
No official stats on baby Johnson have yet been released.
Johnson is already a father to 14-year-old girl Simone from his first marriage. So I'm wondering how much he remembers about caring for a newborn? Like, does he recall anything about being up all night? If not, there's no doubt he'll get up to speed really soon!
Here's wishing Johnson and his family every happiness as they enjoy their new bundle of joy. And hey, Dwayne, if you're reading this, I do have a baby name suggestion, and a word of advice for you. How about "The Stone?" And, no bench-pressing the baby until she's at least a few days old!
