Actor and wife welcome new baby and announce cute name!

Mark-Paul Gosselaar (that’s Zack Morris to us) is a dad again!

Less than two weeks after THAT epic Saved By The Bell reunion, the actor and his wife have welcomed a little girl to their family. 

The actor and his wife Catriona McGinn have welcomed their fourth child and the proud dad took to Twitter to announce the news: “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!”

Aww, what a cute name!

The Saved By the Bell actor is already a dad to 16-month-old Dekker as well as Micheal (10) and Ava (8) from a former marriage.

Congratulations to the happy family on their lovely news!
