Rick Springfield, the 76-year-old "Jessie's Girl" singer, has gone viral for performing shirtless during a recent show, showcasing a remarkably toned and ripped physique. Fan-captured footage from a June 14 concert in Indiana, which Springfield reposted, shows him wearing only leather pants and a guitar, prompting widespread praise for his fitness. The video caught the attention of Joe Rogan and Tommy Lee, who expressed amazement and called his appearance and energy "inspirational." Springfield responded to the clip with appreciation, writing "Good vibes appreciated!" He has previously discussed his fitness regimen, telling People in February 2025 that he exercises every day and follows a mostly pescatarian diet with limited alcohol. He noted that performing with his band serves as a two-hour aerobic workout and that he uses Planet Fitness locations while on tour to stay in shape.
