Dwayne Johnson has welcomed his third daughter — and he’s right back in newborn mode. The actor better known as “the Rock” announced the arrival of his second child with Lauren Hashian by sharing a photo of dad and baby sweetly cuddling skin to skin. The hulking star is seen peacefully holding little Tiana Gia Johnson to his tattooed torso as he sits in his wife’s hospital bed. The “blessed and grateful” dad — who also has 2-year-old Jasmine with Hashian and 16-year-old Simone Alexandra Johnson from his marriage to Dany Garcia — marveled over bringing another “strong girl into this world.” The actor, 45, said Tiana “came into this world like a force of nature,” and called his future wife Hashian a rock star. Big truck, big muscles, big heart.
