Out of curiosity, I recently watched the pilot episode of "Sam and Cat", where Ariana Grande is one of the co-stars. In that episode, Katy was mentioned!! I do know that currently, Katy and Ariana are friends, and that they are big fans of each other. Does anyone know if Katy and Ariana were friends at the time that episode was shot? Or, was Katy aware that she was mentioned, and maybe that caused her to watch the show and become a fan of Ariana? I'm not sure how Katy would have otherwise known about Ariana at the time. Ariana's start was in a Broadway show called "13", but it's unlikely that Katy ever saw it (she never lived anywhere near New York City, and was not famous at the time). I assume that Ariana was already a fan of Katy, so maybe that was why she was mentioned. Anyone know? Thanks.
