Mark Paul Goselaar is an Excited Dad with a New Bun in the Oven

Saved by the Bell alum Mark Paul Goselaar will be expecting his second child with wife Catriona McGinn. This will be Goselaar's fourth child to date, as there were two more from his previous marriage.

The actor revealed the news while attending Disney on Ice's Let's Celebrate with his family in L.A. on Thursday, Dec. 11.

"My wife is due in February with another baby," Gosselaar, 40, told Us. "I'm very excited!"

In 1996, Gosselaar married former model Lisa Ann Russell. Together they have two children but after 14 years of marriage, the couple announced their separation in early June 2010. Gosselaar filed for divorce in the same year and was finalized on May 2011.

Goselaar and McGinn, an advertising executive, have been married since 2012 and shared one son, Dekker Edward, 14 months. The couple is also keeping the sex of their new bun in the oven. "We have told our families," the actor said, "but we haven't told them the name."

Gosselaar also shares son Michael, 10, and daughter Ava, 8, with ex-wife Russell.

The Franklin and Bash actor is proud to say that he had a lot of practice in changing diapers over the years. He even joked that he has been doing this dirty job for a decade now.

His eldest child, Michael, is now keeping up with Zack Morris and the rest of the Bayside High kids. "My son just started watching it," Gosselaar told Us. Michael, who was at the event, chimed in: "It doesn't seem like a TV show. It seems like real life. Its not like your normal TV show."

On the other hand, Goselaar's TV series with Breckin Meyer, Franklin & Bash, was cancelled by TNT last Nov 11 after four seasons. The season and show's finale was shown Oct 22. Goselaar is a guest in the long-running crime series, Crime Scene Investigation Season 15, as twins Jared Briscoe and Paul Winthrop.
