Actor Mark-Paul Gosselaar is set to become a father for the fourth time.
The former Saved By The Bell star's wife, Catriona McGinn, is pregnant with their second child.
The tot will join their one-year-old son Dekker Edward, as well as Gosselaar's two other kids from his first marriage to former model Lisa Ann Russell.
The new father-to-be tells People.com, "It's something we're really excited about and we've been planning for awhile."
Gosselaar and McGinn wed in 2012.
