Inside the Latest 'Saved By the Bell' Reunion

— -- The cast of "Saved by the Bell" is as close as ever!

More than two decades after their show went off the air, two of its stars, Elizabeth Berkley and Tiffani Thiessen, remain friendly.

In fact, Berkley, who played Jessie Spano on the series, recently taped a guest appearance on Thiessen's new cooking show, "Dinner at Tiffani's."

"#Love this #woman @tiffanithiessen !!?? watch us this Wednesday on her new show on @cookingchannel #dinnerattiffanis 10pm ET 7pm PST," Spano wrote on Instagram. "#history #friendship #sincewewerebabies ?? #sbtb #mommys"

In the episode, which will air tonight at 10 p.m. on the Cooking Channel, Thiessen teaches Berkley how to make crostini.

“Elizabeth and I used to spend long hours together on the set of 'Saved by the Bell' so it’s nice that we can reconnect years later and really just kinda be ourselves,” Thiessen said in a preview obtained by People.
