Roger Friedman, a reporter with Showbiz 411, was the first to speak on Franklin’s ailing health. Detroit news anchor Evrod Cassimy has also been in touch with Franklin’s family and even spoke to the star herself on Monday.

“I am so saddened to report that the Queen of Soul and my good friend, Aretha Franklin is gravely ill. I spoke with her family members this morning. She is asking for your prayers at this time. I’ll have more details as I’m allowed to release,” Cassimy wrote on Twitter on Monday.

“Still praying,” Cassimy Tweeted on Tuesday.

While rumors of an illness circulated over the last few years, Franklin remained tight-lipped on her condition.

“Aretha Franklin has been the Matriarch of the Franklin family since the passing of all of her siblings,” Quinn adds. “The love she has for her family is above reproach and was evident in the warm smiles she was able to share with her nephew during his very brief visit two weeks ago.”
