According to E! Online, the unnamed newborn is healthy and has already gotten her 43-year-old dad all worked up.
"Dwayne was very emotional and excited seeing his newborn daughter for the first time, says an insider, adding that the proud dad is thrilled for mom and baby to both be doing so well. Both parents are said to be beyond happy for this next chapter in their lives."
This is Dwayne's first child with Lauren, but his second overall. He has a 14-year-old daughter named Simone with his ex-wife Danny Garcia.
In case you didn't know... Johnson started dating Hashian (officially) in 2007, a short while after he and Garica divorced. They'd been married for 10 years prior to that and welcomed their daughter in 2001.
