Former public protector Thuli Madonsela has joined the worldwide chorus of well-wishes and prayers for ailing US musician Aretha Franklin, after reports emerged on Monday that the gravely ill star was surrounded by concerned family.

According to CNN, Aretha is in hospice care at her home, where she is being looked after by health professionals, friends and family.

A report by the Mirror UK said the star is in "the final stages of a devastating eight-year battle with pancreatic cancer" and was receiving around the clock treatment.
