Sylvester Stallone's son Sage Stallone has died.
The 36-year-old was found dead at his apartment in Hollywood, according to the New York Post.
Stallone issued a statement through his publicist Michelle Bega which read: "Sylvester Stallone is devastated and grief-stricken over the sudden loss of his son Sage Stallone. His compassion and thoughts are with Sage's mother, Sasha.
"Sage was a very talented and wonderful young man. His loss will be felt forever."
According to TMZ, law enforcement sources have stated that although "numerous empty pill bottles" were found at the house, but Sage's death does not appear to be a suicide, with no note found at his home.
Sage made his acting debut opposite his father in Rocky V, playing the part of Rocky's son Robert Balboa.
He featured with his dad again in Daylight, and went on to direct, produce and write.
An autopsy is scheduled to take place within the next 48 hours.
