The 39-year-old was very vocal on the social media site leading up to his son's arrival — admitting he had to rush from his duties as X Factor host straight to the hospital.

As soon as he arrived, Mario started taking pictures and sharing them with his 840,000 followers. 
One pic showed him between his mom and Courtney's mom. The trio all had on the appropriate hospital gear. 

Another featured him next to Courtney in bed as they waited for the doctor.

Shortly after Dominic made his way into the world, Mario went out to celebrate at a local bar.

The duo, who wed last December, announced Courtney's second pregnancy earlier this year. 
In July, Mario told Life & Style he was taking good care of his leading lady. 
"She's doing great," he told the mag. "I pamper her all the time anyway, but it just goes up to another level when she's pregnant."
As for Mario, he adores fatherhood — and admitted he'd like to add "at least four more" kids to their brood. 
"I love [being a dad] more than anything," he says. "…The whole experience is so amazing."
