Mario Lopez loves the family-of-four he’s created with wife Courtney Lopez, but the host of ‘Extra’ admits he’s eager for a third baby!

“Well I’m working on it,” Mario told ‘Life & Style’ when asked about his plans for another. “Hopefully it will work out for us. We’ll see. I’d like a couple.”

The two are already parents to four-year-old daughter Gia and 16-month-old son Dominic — who Courtney claims “terrorizes the house.”

Gia and Dominic show their Steelers pride.

“We nickname him ‘Wreck-It Ralph,'” she told ‘Life & Style.’ “He likes to jump off of things, try and break things, hit things.” But Gia, on the other hand, “is very protective [of Dominic]. She is such a good big sister,” Courtney shared.

A dynamic Mario also talked about his ‘Saved By the Bell’ co-star Tiffani Theissen, who is expecting her second baby.

“The second one — that’s when it gets real,” the 41-year-old, who’s teamed up with avocado brand Avocados From Mexico to create guacamole recipes, confessed. “It’s a game-changer.”
