Zack Morris and his non-Kelly Kapowski-looking wife, Catriona McGinn are expecting their first child together this September.

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

Gosselaar has two children with ex-wife Lisa Ann Russell – Michael, 9 and Ava, 6.
