Devon and Raven is a canon pairing within That's So Raven and a non-canon within the spinoff, Raven's Home. Raven and Devon had a long history with one another, starting from That's So Raven, ending with their divorce, somewhere between the intervening years.
Later revealed, Raven and Devon split ways after being married through their futures, and how Raven and Devon thought that it was time to raise their kids to be who they are. Although this is the case, Devon and Raven are still close friends.
