Nickelodeon is hard at work putting together an All That revival series with original series breakout star Kenan Thompson as an executive producer, but Thompson won't be the only familiar face involved in the project. Because how are you gonna have Kenan without Kel?

Kel Mitchell confirmed the news that he will appear in the All That revival on Instagram Monday night, writing, "Guess the cats out the bag. Let's do this @kenanthompson & @brobtv It's bout to be Lit! We Back! #Allthat #Nickelodeon #Snick #TeamJesus #gogetthemblessings Thank you Jesus! God is Good!"

Thompson was the first to spill the beans, confirming the news in an interview with Page Six. "Whoever's down to come do it, we would love to have them in my opinion," the Saturday Night Live star said. "I know Kel [Mitchell's] coming back, and I remember working close [sic] with Josh Server as well. I think all the old cast members should come support the new cast members. That's just how it should go."

Brian Robbins, who co-created All That, seemed confident that old cast members would reappear in the new version when he spoke to Variety earlier this month, saying, "This summer, we are going to bring back a lot of the original cast and the cast through the years, and let them introduce the new cast of All That to the world."

No other cast members have announced that they'll be back to make these introductions, but we're betting on major players like Lori Beth Denberg, Danny Tamberelli and, of course, the previously mentioned Josh Server. Who knows? Maybe we'll even get a surprise visit from Amanda Bynes!
