Mark-Paul Gosselaar confirmed he dated Saved by the Bell costar Elizabeth Berkley, so don’t tell Kelly

Kelly and Zack may have been endgame on Saved by the Bell, but in real life, Mark-Paul Gosselaar was actually dating his other costar, Elizabeth Berkley. Berkley played Jessie Spano, Zack’s next-door neighbor who often served as the (much-needed) voice of reason in the group. And while on-screen Jessie and Zack didn’t share much romantic chemistry, off-screen was another story.

"You’re in an environment — you know how it is, Gosselaar told Anna Faris on the January 22nd episode of her podcast Anna Faris is Unqualified. “When you’re working on a set, and we were young, there’s no one around really. I mean, you work and live in a bubble.

He went on to explain that spending so much time at work restricted the dating pool: “You’re in L.A., right? You’re in your cars and you come to set and you do your work and you’re with these beautiful women and then you go back in your car…and you’re not going to school, so you don’t have a lot of choices.” Gosselaar also explained that he didn’t socialize much outside of work, and that his momager drove him to set every day.

While the image of Jessie and Zack dating for more than an episode may be jarring to some fans, in 2009, People reported there may have been even more off-set coupling.

“All of us dated at one point or another," Gosselaar told the outlet. "It was incestuous!"

Hey, Tiffani Thiessen did confirm that Gosselaar was a good kisser. Honestly, we need a full documentary feature on all of this, STAT,
