Sylvester Stallone's half-sister, Toni-Ann Filiti, died Sunday night at age 48 after an extended fight with lung cancer, according to multiple news reports.
It's been a summer filled with tragedy for The Expendables 2 star, whose son Sage Stallone also passed away at 36 of yet-to-be determined causes.
Filiti entered UCLA's ICU August 10, where doctors had "done everything" they could. Prior to her hospitalization, she had been living with her mom.
Filiti's son and Stallone's nephew, Edd Filiti, had accused the actor, on Facebook, of neglecting Sage Stallone in recent years. He recanted that claim.
Filiti was married twice and had a son, Edd, with second husband Louis D'Alto, an actor who appeared in several Stallone vehicles. They split in 2001.
Our thoughts go out to Stallone and his family.
