The newborn is the "Furious 7" star's first child with his longtime partner, Lauren Hashian, and is a half-sister for the actor's 14-year-old daughter Simone, with his ex-wife Dany Garcia, reported E!Online.
The 43-year-old father was emotional as he witnessed the birth, while both mother and baby are said to be doing well.
The news comes just days after singer-songwriter Lauren opened up about her impending motherhood in a sweet post on Instagram.
The reports of Lauren's pregnancy first emerged in September, but Dwayne only confirmed the happy news in November.
