Another baby has joined the Bayside High gang!
The "Saved by the Bell" actor also has two kids from a previous marriage, son Michael Charles (10) and daughter Ava Lorenn (8).
Gosselaar shared an official baby announcement on Twitter:
So in love with our new baby girl, Lachlyn! Born last night 2/17 Mum and baby are healthy and happy. 2 boys, 2 girls, too perfect!

Baby Lachlyn arrives a day after Jimmy Fallon shared a photo of his second daughter, Franny, on Instagram. The actor and the comedian recently struck comic gold with a mini "Saved by the Bell" reunion on The Tonight Show.
Another fellow Bayside High alum, Tiffani Thiessen (aka. Zack's long-time love Kelly Kapowski), is also expecting a baby this year!
