In a classic "Kenan & Kel" mixup, Kel (Kel Mitchell) is mistaken for a hairdresser and ends up doing Spears' hair. Kel gets a little too into his ruse, but promises to make her into a "teenage singing superstar" as Brit points out, "I...kinda already am."

Next thing she knows, she's got green highlights and she's screaming into a mirror in horror like Joan Crawford finding a grey hair.
