Friends Forever! Mark-Paul Gosselaar and Tiffani Thiessen Do a Double Date

It's Saved by the Bell's Zack and Kelly, together again! Former costars Mark-Paul Gosselaar and Tiffani Thiessen reunited for the finale of her cooking show, Dinner at Tiffani's. For the buzzed-about episode, which airs tonight, the pair had a double date in the kitchen with their spouses, Catriona McGinn and Brady Smith.

Mark-Paul isn't the first Saved by the Bell actor to appear on Tiffani's show — Mario Lopez joined her in the kitchen back in 2014, and Elizabeth Berkley made an appearance in early 2015. Meanwhile, the whole gang got back together for an epic Saved by the Bell reunion on The Tonight Show last August, prompting all kinds of cute moments among the group.

Tune in tonight to catch the reunion, and be sure to check out Mark-Paul's sweet family snaps plus adorable pictures of Tiffani's kids.
