Dwayne Johnson/Instagram "Rampage" star Dwayne "The Rock" Johnson took to Instagram to reveal the birth of his daughter, Tiana Gia. "I was raised and surrounded by strong, loving women all my life, but after participating in baby Tia's delivery, it's hard to express the new level of love, respect and admiration I have for @laurenhashianofficial and all mamas and women out there," Johnson wrote.
