The actor, best known for his roles as Zack Morris on 90s hit show Saved By The Bell and Franklin and Bash, welcomed his first child with McGinn last year – a boy named Dekker Edward.
Gosselaar is already dad to Ava Lorenn (8) and Michael Charles (10).
The star recently rejoined his former cast mates on Jimmy Fallon for an incredible mini-reunion of Saved By The Bell.
