Dwayne "The Rock" Johnson and his girlfriend Lauren Hashian have welcomed their first baby!

Hashian gave birth to a healthy baby girl Wednesday, a source told E! News. This is the first child for the couple and the second for Johnson, 46, who has a 14-year-old daughter Simone with ex-wife Dany Garcia. The source revealed that Johnson was very emotional and excited when he saw his newborn little girl for the first time and was thrilled to know that his girlfriend and daughter were doing so well. The two can't wait to be parents and start this new chapter of their lives.

Just a few days ago, the singer-songwriter reposted The Rock's baby announcement post from a few weeks ago, writing, "I know I'm late to the party...Sometimes life gets full and busy in the best ways. 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. And like Bid Daddy says-couldn't be prouder of all the kickass women she's going to have around her! And Men of course #LetsJustHopeBigDaddyDoesnt=20lbBaby."

When Johnson originally posted the photo in November, he wrote, "I was raised by and live with amazing and strong women, so the universe felt we needed one more. IT'S A BABY GIRL!! THANK YOU guys so much for the awesome support and love you've send @laurenhashianofficial and myself from around the world. We're so grateful for this blessing and thrilled to share the news with y'all."

When news first broke that they were expecting in September, the baby was assumed to be due sometime in January, as HNGN previously reported. "Dwayne and Lauren couldn't be more thrilled," a source said. "They've been rock solid for about nine years now and felt it was time to expand their family. Lauren's brother also expecting a baby, so the entire family is overjoyed!"
