Another death in the family for Sylvester Stallone

Sylvester Stallone has suffered the loss of another loved one.

Six weeks after his 36-year-old son, Sage, died unexpectedly, the actor has lost his only sister. Toni Ann Filiti, the 48-year-old half-sister of “The Expendables 2” star, succumbed to lung cancer on Sunday. She died at their mother Jackie Stallone’s Santa Monica home after choosing to leave UCLA hospital.

“I was holding her in my arms,” Jackie, 90, told the New York Daily News. “I had just washed [her] face and told her how pretty she looked, and she just fell asleep. … She’s too young to go, but she wasn’t feeling any pain.”

Jackie, an astrologer and psychic, personally broke the news of Toni’s death to her famous son. “He said he can’t take any more pain,” she told the newspaper. “He said he’ll always be there for her son. ... What a terrible month – first Sage and now Toni. It’s hard. At least they’re together now in heaven.”

On July 13, the actor’s son Sage Moonblood Stallone was found dead in his Studio City, California, apartment. Authorities said there were no signs of foul play, but there were reportedly numerous pill bottles nearby. Sasha Czack, Sage’s mother and Sly’s first wife, said Sage was in pain after dental surgery. A toxicology report is pending.

After Sage’s death, Sly took an extended family vacation, traveling to Europe with his third wife, Jennifer Flavin, and their three daughters. He later joined his “Expendables 2” cast mates, including Arnold Schwarzenegger, Jean-Claude Van Damme, and Jason Statham to promote the action flick, which has been tops at the box office the past two weekends.

"It's tough. It's very tough," the 66-year-old told "Good Morning America" about the loss of his son. "It's a horrible situation, but time hopefully will heal and you try to get through it. It's just something that's a reality of life."

Unfortunately, it’s a reality he’s experienced a lot lately.
