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."
