#25: Kel Mitchell
Kel Mitchell is best known as one half of the sitcom duo Kenan & Kel, which ran on Nickelodeon from 1996 to 2000. But did you realize Kel had been an original cast member on the Nick sketch comedy show All That? He was also nominated twice for a Daytime Emmy Award for voicing T-Bone in the cartoon series Clifford The Big Red Dog.

Kel married actress and writer Tyisha Hampton in 1999. They have two children, a son and a daughter. After their divorce in 2010, Kel began dating rapper Asia Lee and the couple married in 2012. They also have two children, a daughter, and a son. They also created a show together, The Back House Party. Is it just us, or does he look exactly the same as he did two decades ago?
