Sylvester Stallone has two sons, Sage and Seargeoh, with first wife Sasha Czack, and three daughters—Sophia, Sistine and Scarlet—with Jennifer Flavin. Sage pursued acting and filmmaking before his 2012 death; his daughters have worked in entertainment.
Sage played Rocky's son in Rocky V. He died unexpectedly on July 13, 2012; reports later confirmed heart disease as the cause. Seargeoh was diagnosed with autism at age 3 and has largely stayed out of public view. In a September 2026 interview on The New York Times podcast The Interview, Stallone described continuing grief and guilt over Sage's death.
Sophia graduated from USC with a fashion degree and founded Callisto Media, which is producing two series for MGM; she announced her engagement to Michael Sheehan in August 2026, and Stallone praised him publicly on Sept. 27. Sistine has worked as a model and actor, while Scarlet has acted in Tulsa King since 2022 and appeared in the 2025 films Hunting Season and Gunslingers.
