Mark-Paul Gosselaar will be a dad because his wife Catriona McGinn is pregnant with their first child together in September. They tie knot last July in Santa Ynez, Calif.
Mark-Paul Gosselaar tells PEOPLE, “We are all really excited for the arrival of our new addition. 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.”
