Mark-Paul Gosselaar and second wife, Catriona

Another baby has joined the Bayside High gang!

Mark-Paul Gosselaar, aka. Zack Morris, just welcomed a daughter, named Lachlyn Hope. This is Gosselaar's second child with his second wife; they have a 16-month-old son, Dekker Edward.

The "Saved by the Bell" actor also has two kids from a previous marriage, son Michael Charles (10) and daughter Ava Lorenn (8).

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!
