The 43-year-old Fast and Furious star was said to be 'very emotional and excited' at the birth of his daughter on Wednesday.
The Californian wrestler-turned-actor already has a 14-year-old daughter, Simone, from his marriage to ex-wife Danny Garcia.
However, this is the first baby for Dwayne and his partner Lauren, 31, who have been dating 10 ten years.
Exciting baby news for The Rock! But who else has made a special baby announcement this week?
Last week Lauren had posted to her Instagram account saying; 'So grateful and in awe of this time. To experience creating a little life is just incredible... this beautiful cycle of life and womanhood beginning again.'
Whilst little is known about the couple as they have been infamously private about their home-life - Lauren's pregnancy was only announced in September - Dwayne revealed to Esquire magazine that he has a 'solid' support network.
He said; 'I've lived with my long-term girlfriend Lauren going on like eight, nine years now. We spend a lot of time with my daughter in Florida, Simone... I always like making sure we find the balance and my home life is in there.'
Had the best dinner w/ my daughter Simone at one of our favorite spots. Life's crazy and complicated, but this amazing, loving, protective one of a kind father/daughter bond we have keeps me grounded and balanced. #GratefulMan #FatherDaughterBond #LifesBlessings #NowLetsOrderEveryDessertOnTheMenu #CuzWeCray #Prime112
Dwayne and Lauren first met on the set of The Game Plan in 2006. On 1st June 2007, Dwayne and wife Danny annouced they were separating and intended to remain friends for the benefit of their daughter.
Soon after the divorce was finalised, Lauren and Dwayne's relationship was made public, and the pair have been inseperable ever since.
Dwayne went through an emotionally tough period last year when best friend and acting co-star Paul Walker died in a car crash in California. He is also a close friend of actor and former Governor of California, Arnold Schwarzenegger.
