Dwayne Johnson and his longtime girlfriend, Lauren Hashian, welcomed a beautiful baby girl named Tiana Gia Johnson earlier this week, and she could not be any cuter. On Monday, Dwayne announced her exciting arrival with a photo of himself cradling his daughter in the hospital, and hours later, his mum, Ata Johnson, shared an Instagram album of her own. Not only does it give us a closer look at baby Tiana, but it also features Tiana's two older sisters, 2-year-old Jasmine and 16-year-old Simone. "My 3-heart Of hearts! ❤️❤️❤️," Ata captioned the sweet snaps. "My heartfelt love & gratitude to Lauren & Dwayne, and most of all, thank you God, from this very happy & proud grandma." Aw! Is your heart bursting yet?
