We asked the BuzzFeed Community to tell us a famous song they didn't realize was about a celebrity. Here are some of the best responses:
1. "Ms. Jackson" by Outkast was an apology to Erykah Badu and her mother after Badu and Andre 3000 broke up.
2. "California Gurls" by Katy Perry was aimed at Jay-Z and Alicia Keys as a response to their "Empire State of Mind." She wanted there to be a song to represent California.
4. "Killing Me Softly" by Norman Gimbel was inspired by a young singer named Lori Lieberman who had seen Don McLean perform and told Gimbel that it was an intensely moving experience. So in essence, it's about Don McLean.
