Posting a sweet picture of him and his love, the actor said: 'Bring on more estrogen in our home.

'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 sent @laurenhashianofficial and myself from around the world.'

He continued: 'We're so grateful for this blessing and thrilled to share the news with y'all.'

He added the hashtags: '#MeAndPuppyHobbsAreTheOnlyDudes #Proud2xPapaBear #JustOverHereMakingBabiesAndStuff.' 

While just how little their little girl is has not been revealed, Lauren said earlier this week she hoped her baby was not going to take after its father.

She wrote on Instagram: 'Like Big Daddy says - Couldn't be prouder of all the kickass women she's going to have around her! And Men of course ;).. #LetsJustHopeBigDaddyDoesnt=20lbBaby'

The 31-year-old singer and model said despite her concerns she was loving being pregnant. 

She also wrote: '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.'

Lauren met the San Andreas' star back in 2006 while filming, The Game Plan.

Longtime love: The couple (seen here in May) have been dating almost a decade and met while the star was filming The Game Plan in 2006

The Rock was still married to his college sweetheart Dany at the time and filed for divorce a year later.

Shortly after the divorce, Dwayne and Lauren started dating but obviously there were no hard feelings as Dany remains the actor's manager.

Lauren is a signer and comes from musical roots as her father is John 'Sib' Hashian, who replaced Boston's original drummer, Jim Masedea, but was dumped when Jim returned.
