Mark-Paul Gosselaar: Then
Mark-Paul Gosselaar as Zack Morris was the definition of a ‘90s teen heartthrob, with his coiffed blonde hair, chiseled jawline, and mildly bad-boy attitude. Gosselaar was just 14 when he was cast in the “Saved by the Bell” predecessor show, “Good Morning Miss Bliss,” and he grew up over the next several years on both “Saved by the Bell” and “The College Years” spin-off.
