Nickelodeon Stars: Where Are They Now?

Young Ariana Grande

Unarguably the most successful star to emerge from Nickelodeon, Ariana Grande got her start on TV as Cat Valentine in Victorious. She then starred as Cat again in Sam & Cat, which ran for one season. Ariana is a natural brunette but had to dye her hair velvet red for the role of Cat Valentine because the rest of the cast were brunette and the producer didn’t want everyone to have brown hair.
