One pic showed him between his mom and Courtney's mom. The trio all had on the appropriate hospital gear.

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."
