Sylvester Stallone on Son's Death: 'It's A Horrible Situation'

It's been just over one month since Sylvester Stallone's son, Sage, was found dead in his home. Now the actor has spoken out about the effect the death has had on his life and how he is coping.

"It's tough. It's been very tough," he said during an interview on "Good Morning America." "It's a horrible situation but time, hopefully, will heal and you try to get through it. It's something that's a reality in life."

Stallone has also been busy working to promote his latest action-adventure film, "The Expendables 2." He, along with friends Arnold Schwarzenegger, Jean-Claude Van Damme, Chuck Norris, and Bruce Willis got to play with new weapons and seemingly had a great time filming the movie.

For Stallone, though, his focus is now on his work.

"It's important to get back and try to start re-living your life. Otherwise, you can go into a spiral," he explained.

Fellow actor and California governor Schwarzenegger was glad to have Stallone back in the game.

"It was great … because the spotlight was not on me. I was very appreciative that Sly was interested in having me in the movie," he told GMA. "They thought that being eight years out of the game, that I maybe would not know how to hold a gun anymore. Stallone was coming over, saying, 'Here's how you hold it,'" Schwarzenegger joked.

Sage was only 36 when he was found dead in his home; he was one of two sons born to Stallone and his first wife Sasha Czack. Though the cause of death is not known, many have suspected an overdose. According to one report, empty bottles of prescription drugs were found near his body.

Sage Stallone was laid to rest in California on July 21 at the St. Martin of Tours Catholic Church. He is survived by his brother, Seargeoh, and three sisters, Sophia, Sistine, and Scarlet.
