When pop stars, movie icons, and other celebrities appear on our favorite TV shows, it’s always a special cherry on top. Celebs like Jennifer Lopez, Britney Spears, Cher, and even Elon Musk are just a few famous people who tried themselves at TV show acting at least once. Whether they’re playing themselves in a small role or impersonating a character, they liven up shows with their appearance, and we can’t wait to see them on screen again.
