*Joni Sledge, one-fourth of the sibling group Sister Sledge, died from a preexisting medical condition, according to TMZ.

Citing law enforcement sources, the website reports that there was no foul play, and the 60-year-old’s cause of death will be listed as natural.

Joni was found dead in her Arizona home on Friday.

The exact nature of the preexisting medical condition is still unclear, but an autopsy was not ordered, according to TMZ, because her doctor signed off on “natural causes.”
