It's Saved by the Bell [1]'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 [2]. 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 [3] actor to appear on Tiffani's show — Mario Lopez joined her in the kitchen [4] back in 2014, and Elizabeth Berkley made an appearance [5] in early 2015. Meanwhile, the whole gang got back together for an epic Saved by the Bell reunion on The Tonight Show [6] last August, prompting all kinds of cute moments among the group [7].

Tune in tonight to catch the reunion, and be sure to check out Mark-Paul's sweet family snaps [8] plus adorable pictures of Tiffani's kids [9].
