Sylvester Stallone appeared on Good Morning America to promote his upcoming film The Expendables 2, when he addressed his 36-year-old son Sage's recent death for the first time.

While sitting alongside his action co-stars, Stallone told GMA:

    "It's tough. It's very very tough. 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."

Sage Stallone was found dead at his California home on July 13.
