John C. Reilly's Son Leo Stars in Olivia Rodrigo Video

Leo Reilly, son of actor John C. Reilly, has stepped further into the spotlight in 2026, featuring in Olivia Rodrigo's recent music video. He first gained widespread public attention in 2020 when side-by-side photos with his father went viral, sparking interest in his burgeoning music career under the moniker LoveLeo and his younger brother, Arlo.

Having started making music as a teenager, Leo has since released several singles and EPs, with his debut single "BOYFREN" achieving significant success in 2020. He even landed a major-label record deal shortly after. Leo previously studied fashion design, inspired by his interest in basketball shoes and a desire to create unique clothing, which led him to develop skills in sewing and customizing apparel.

Leo has expressed a desire to be recognized for his own achievements rather than solely through his family name, noting that his pursuits are often in a different realm than his father's acting career. He acknowledges the connection can be a discovery point for fans but prefers not to lead with it, aiming to be seen as an individual artist. His younger brother, Arlo, maintains a more private profile, engaged in modeling with Click Model Management and pursuing fashion design, including an artistic project called "Touching" in 2023.

John C. Reilly himself has emphasized Leo's independent success, stating in a 2022 interview that Leo achieved his accomplishments without leveraging his father's fame, with neither the record label nor signing parties initially aware of their familial connection.
