Mark-Paul Gosselaar’s wife, Catriona McGinn, is pregnant

Mark-Paul Gosselaar and his new wife, Catriona McGinn, are expecting their first child together.

This will be the “Franklin & Bash� star’s third child and the first for the advertising exec, whom he married in July 2012 at a Santa Ynez winery.

The “Saved By the Bell� alum, 39, and McGinn “are thrilled to announce they’re expecting their first child together in September,� his rep told People.

“We are all really excited for the arrival of our new addition,� Gosselaar told People. “We’ve always wanted a big family. The kids are looking forward to a little sibling, and are asking a lot of funny questions right now.�

Gosselaar, who will forever be Zack Morris in the Ministry’s mind despite his resistance, has two young children, Michael and Ava, from his previous, 14-year marriage to Lisa Ann Russell.

“Catriona’s great with my kids,� the actor said when he and McGinn got engaged. “My kids absolutely adore her.�

And in other “Saved By the Bell� news, the “Boy Meets World� spinoff has reignited interest in a “Saved By the Bell� reunion/spinoff. And we are totally OK with that.
