SYLVESTER STALLONE'S son SAGE was found dead in his Los Angeles home by a maid on Friday. He was only 36 years old. The cause of death is unknown at this time.
--Sylvester's rep issued a statement saying he's, quote, "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."
--A source adds, quote, "This came completely out of the blue. Sylvester did not see this coming for one minute. Sage was healthy, and Sylvester thought he was doing really well, this came from complete left field.
--"Sylvester was very close to Sage and he is absolutely overwhelmed with grief by his death. He is totally stunned and still in a state of shock."
(--Sasha was Stallone's first wife. They also have a son named Seargeoh who is autistic. Stallone also has three daughters with his current wife, Jennifer Flavin. In between Sasha and Jennifer, Stallone made the unwise choice of marrying Brigitte Nielsen.)
--Sage Moonblood Stallone . . . yes, that's his real middle name . . . appeared with his dad in two movies. In 1990, he played Rocky's son in "Rocky 5". And he was in Sly's 1996 action flick "Daylight".
--After that he co-founded Grindhouse Releasing, which was dedicated to restoring old horror and cult movies for theatrical re-release and DVD.
--Sage did act in some low-profile stuff in recent years, but he turned down the opportunity to play Rocky's son again in "Rocky Balboa" because of his Grindhouse obligations. (--The part went to Milo Ventimiglia.)
