The Rock is a dad again: Dwayne Johnson revealed that his he and his longtime girlfriend, Lauren Hashian, have welcomed a baby girl.

Johnson made the exciting announcement on Instagram on Monday, where he shared a sweet snap of himself snuggling his newest addition, Tiana Gia Johnson. The star -- who already has the perfect movie on his resume to share with his little girl someday -- wasted no time in praising Hashian for giving birth to their second child.

Skin to skin. Our mana. Blessed and proud to bring another strong girl into this world. Tiana Gia Johnson came into this world like a force of nature and Mama @laurenhashianofficial labored and delivered like a true rockstar. 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. 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. Its a life changer and the respect and admiration you have for a woman, will forever be boundless. 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. 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. Oh and one more thing.. you're gonna love rollin' in daddy's pick up truck. #TianaGiaJohnson???? #3rdDaughter #BlessesAndGratefulMan #ImInTROUBLE

The star has not been shy in recent years about sharing intensely personal details about his life with his fans, and the same was true in announcing the birth of his third daughter. In addition to lauding Hashian, he shared some special words for Tiana herself.

"[Y]ou have my word, I'll love, protect, guide and make ya laugh for the rest of my life," the star said. "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."

Tiana is Johnson's third child, and second with Hasian. She joins big sisters Simone, 16, and Jasmine Lia, 2.
