Mark-Paul Gosselaar Expecting Third Child, First With Wife Catriona McGinn

The world should prepare to have another little Zack Morris running around.

Mark-Paul Gosselaar and his wife Catriona McGinn have announced they are expecting their first child together. Gosselaar's rep confirmed that the couple will welcome their new bundle of joy in September, according to Us Weekly.

The "Saved by the Bell" star, 39, already has two children with ex-wife Lisa Ann Russell: 9-year-old Michael and 6-year-old Ava. Gosselaar and Russell divorced in May 2011 after 15 years of marriage, and Russell is now married to "Survivor" host Jeff Probst.

Gosselaar, who currently stars on "Franklin & Bash," said McGinn is "great" with his kids, who "absolutely adore her."

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

Gosselaar and McGinn, an advertising executive, got married in July 2012 after being engaged for a year.

We're excited for you guys and all, but we're really just hoping this new entry in Gosselaar's life will soften him enough to agree to a "Saved by the Bell" reunion.
