Sylvester Stallone’s Half Sister Dead: Toni-Ann Filiti’s Death Follows Passing of Sly’s Son Sage

Poor Sylvester Stallone.

The Hollywood megastar is still reeling from the tragic death of son Sage Stallone, and now he must mourn the loss of his half-sister, Toni-Ann Filiti.

RadarOnline reports that she succumbed to lung cancer yesterday.

Toni-Ann had been living with the mother she shared with Sylvester, Jackie Stallone.

Signs of prescription drug abuse surrounded the death of Sage, and coincidentally, Toni-Ann also was accused of pill misuse. Just more drama to add to the tragedy plaguing Sylvester lately.
