Mark-Paul Gosselaar's house is about to get that much fuller as the former Saved By the Bell star is currently expecting his fourth child, E! News can confirm.
"It's something we're really excited about and we've been planning for awhile," he told People magazine during the Disney on Ice Presents Let's Celebrate! event in Los Angeles.
Gosselaar also shared that he and his pregnant wife, Catriona McGinn, are currently in nesting mode and are as prepared as they can be for their exciting arrival.
"We're doing some tweaks to the house and some things to prepare for the room," he shared.
"But we're old pros at this now. How do you prepare other than get as much sleep as you can?"
This marks the actor's second child with his second wife, McGinn, as she gave birth to their son Dekker Edward back in 2013.
Gosselaar is also a proud father to Ava Lorenn, 8, and Michael Charles, 10, from a previous marriage.
But Gosselaar told the mag that he loves "big families" and that he can't wait for his brood to expand.
"There's nothing better than a happy child. Children make life better—not at the beginning—but as they sleep through the night, that makes life better."
And as far as the upcoming holidays are concerned, Gosselaar is even more ecstatic for this exciting time in his kids' lives.
"Waking up in the morning and seeing their faces when they see gifts…all the holidays are so much more special with children."
Congratulations and happy holidays to the Gosselaar family!
