Mark-Paul Gosselaar welcomed a son with wife Catriona McGinn on Monday, ABC News has confirmed.
Dekker Edward Gosselaar joined the family yesterday around noon in Los Angeles, Calif. The "Saved by the Bell" star, 39, said that he and his advertising executive wife are "overjoyed" by the new addition.
"He is healthy and just perfect - all we could ask for," he added.
Gosselaar has said in the past that he and his wife always wanted a big family and now he has three children. In addition to Dekker, he has Ava, 7, and Michael, 9, from his relationship with ex-wife Lisa Ann Russell.
Gosselaar and McGinn married last July.
