Mark Paul Gosselaar and Tiffani Thiessen
For a certain generation, this Saved by the Bell duo was the most shipped couple on TV — before shipping even existed! For Gosselaar, finding a role after his Zack Morris days proved to be tough, but after a few stumbles (including the ill-fated College Years), he ultimately scored roles on NYPD Blue and Raising the Bar, the latter of which led to his current starring role on Franklin & Bash. For Thiessen, she went the anti-Kelly Kapowski route as the sexy and mischievous Valerie Malone on 90210. A few bit parts later, she landed on USA's popular White Collar.
