Every artist who has appeared on the Billboard Hot 100 has played a part in the history of popular music, but some leading men and women have had special roles on the singles chart. Dozens of actors who sing have found berths on the Hot 100, from Tab Hunter and Debbie Reynolds in the ’50s to Donald Glover and Bradley Cooper in this millennium. There are also singers who act – think Whitney Houston, Justin Timberlake, Diana Ross and Tim McGraw – but that’s a different story. While determining who is an actor who sings and who is a singer who acts is a subjective act, Billboard looked at the entirety of an artist’s career. Which field came first was not a deciding factor – for example, Mark Wahlberg was recording artist Marky Mark before pursuing an acting career, but it is clear he is primarily thought of as an actor today. Here are profiles of 60 artists best known for their acting who have graced the Hot 100 during the chart’s 60-year history.
