AC Slater and Kelly Kapowski, together again!

"Saved by the Bell" alum Mario Lopez took to Instagram to share a snapshot with his former costar Tiffani Thiessen as they cooked up some delicious dishes at the actress' home.

"Loved catching up with my girl @TAThiessen! Had a fun time on her show 'Dinner At Tiffanies' #CookingChannel," he captioned the cute candid.

The Cooking Channel show follows Thiessen as she throws intimate dinner parties at her house for her celebrity friends, including Nathan Fillion, Willie Garson and former "90210" costar Lindsay Price.

Tiffani must have honed her cooking skills after her gig on the hit sitcom because Mario posted a funny tweet after their reunion. "I remember when she could barely wash a grape and now she has her own cooking show... #CookingChannel," he joked.

Lopez recently revealed he had a romantic relationship with Thiessen back in the day while promoting his book, "Just Between Us," on Howard Stern.

"We were in a relationship," Lopez said. "Out of all those girls, that's the one I would have picked," Stern said. "We were pretty slick about it. We weren't holding hands or making out on set."

Who knew their love went beyond Bayside High?!
