The pair shot to fame as the stars of 1990s sketch show All That and they went on to land their own sitcom, Kenan & Kel, which ran from 1996 to 2000. They even starred in 1997 movie Good Burger together, but went their separate ways after Kenan & Kel came to an end.
Mitchell has now revealed the former friends are no longer in contact and fans should give up hope of ever seeing them on screen together again.
He tells TMZ.com, ""The truth is Kenan does not want to be seen with me in any form of media, or even have my name mentioned around him... I have not been upset about this. I respect his choice of wanting to make a name for himself solo.
""There is no bad blood on my side, I'm not declining a reunion, I know the fans love the show and would love to see some type of appearance with us... I just don't see that ever happening because of how he really feels.""
