Sage Stallone Laid to Rest

Sylvester Stallone mourned the loss of his son Sage on Saturday at a private funeral in Brentwood, CA. Family and friends, including Sly’s wife Jennifer Flavin and brother Frank, gathered with the actor at St. Martin of Tours Catholic Church for the service.

Sage's mother Sasha Czack asked that mourners donate money to Autism Speaks in lieu of flowers. His younger brother Seargeoh is autistic.

News of the 36-year-old's death broke on July 13 after he was found dead in his Studio City apartment. He was best known for co-starring with his dad in "Rocky V."

Stallone released a statement last week asking for respect, "When a parent loses a child, there is no greater pain. Therefore I am imploring people to respect my talented son's memory and feel compassion for his loving mother Sasha.”

He added, “This agonizing loss will be felt for the rest of our lives. Sage was our first child and the center of our universe, and I am humbly begging for all to have my son's memory and soul left in peace."
