Sylvester Stallone's son has reportedly died of a drug overdose, aged 36.
Sage Stallone was found at his Studio City home on Friday morning, local time, after he allegedly passed away following an overdose of pills, according to TMZ.com.
Lawyer George Braunstein would only confirm the death but said the cause was still under investigation.
He told website LATimes.com: "We don't have any of the details. He wasn't depressed. He was thinking about getting married. He just had his whole life ahead of him."
Paramedics were apparently called to the home and pronounced him dead at the scene.
Sources claim authorities are trying to determine if the death was intentional or accidental and TMZ were told that his father Sylvester is a "wreck."
Sage famously made his film debut alongside his father in the 1990 movie Rocky 5 - playing the role of Rocky's son Robert Balboa.
He appeared as an actor in several movies, including some with his father, such as Daylight.
