Katy Perry - There are some Glee collaborations that seem so tailor-made that it’s no surprise when they actually happen. Katy Perry is one of them. Her music was used in season one, and the star also spoke about a possible cameo in a recent post on Twitter: "Please! I would love somebody to start that Facebook group and persuade them. I would absolutely love that."
