Sylvester Stallone's son planned to marry his girlfriend "as early as next weekend" prior to his death.
Sage Stallone, 36, was found unresponsive at his home in Studio City, Los Angeles on Friday, and his attorney and longtime friend George Braunstein revealed the actor was "very full of life" and he wanted to tie the knot in Las Vegas in the near future.
He told E!: "He was very creative, energetic and very full of life. We were just joking about how he was going to get married and have a fun marriage. There was nothing dark or depressing, no problems, certainly no financial problems."
Assistant Chief Coroner Ed Winter said prescription bottles were recovered in the investigation, but he did not say what they contained, although George claims Sage didn't drink alcohol or take drugs.
He added: "I never knew him to drink alcohol. I never saw him take drugs. I never knew of anything like that at all."
Law enforcement sources told TMZ that Sage may have been dead for a minimum of three or four days, possibly as long as a week, before his body was discovered by his housekeeper.
But George has dismissed such claims after photos were posted on Sage’s Facebook account just 17 hours before he was found dead.
He explained: "Sage was a really young, very sensitive, and very talented kid. There has been no indication that there was anything wrong in his life."
Sage was Sylvester's son from his first marriage to Sasha Czack, and the pair are said to be "devastated" by the news.
George said: "His mother is devastated. They're trying to sort everything out and plan a funeral. [Sylvester] called, he's upset too. They may be celebs, but they're regular parents. It's tragic."
