Mark-Paul Gosselaar and Tiffani Thiessen of Saved by the Bell
Character names: Zack Morris & Kelly Kapowski
Years dated in real life: Unknown
Being that few people read Screech's autobiography besides Dustin Diamond himself, it's not well known that Saved by the Bell's Zack Morris and Kelly Kapowski, Mark-Paul Gosselaar and Tiffani Thiessen, did indeed date in real life. Yes, apparently this romance extended beyond The Maxx. Ol' Screech claims that the two had an on-again, off-again relationship that lasted up until Saved by the Bell: The College Years, where Mark-Paul met his current wife, who played an extra on this short-lived NBC primetime series.
Imagine if Zack and Kelly got married. We bet Jessie Spano would have been so excited! So excited! So…scared.
