Prince William and Duchess Kate Middleton aren’t the only ones celebrating a new baby. Dwayne “The Rock” Johnson and his longtime girlfriend, Lauren Hashian, have just welcomed a daughter into the world.

The proud dad took to Instagram to make the big announcement, posting a pic of himself holding the tiny newborn. “Skin to skin. Our mana. Blessed and proud to bring another strong girl into this world,” he captioned the photo. “Tiana Gia Johnson came into this world like a force of nature and Mama @laurenhashianofficial labored and delivered like a true rockstar.”

He continued, “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 then added some advice to other parents, writing, “Word to the wise, gentlemen, it’s critical to be by your lady’s head when she’s delivering, being as supportive as you can… holding hands, holding legs, whatever you can do. But, if you really want to understand the single most powerful and primal moment life will ever offer — watch your child being born. It’s a life changer and the respect and admiration you have for a woman, will forever be boundless.”

This is the couple’s second child together (they welcomed Jasmine in 2015) and Johnson’s third overall. (He shares 16-year-old daughter Simone with ex-wife Dany Garcia.)

“And to my third and youngest daughter, Tiana Gia — like I did when your two older sisters Simone Alexandra and Jasmine Lia were born, you have my word, I’ll love, protect, guide and make ya laugh for the rest of my life,” he concluded his message. “Your crazy dad has many responsibilities and wears many hats in this big ol’ world, but being your dad will always be the one I’m most proud to wear.”
