ARETHA FRANKLIN's family says she's "gravely ill" and are "asking for your prayers at this time." They didn't give any more details. CNN says she's in hospice care. Aretha is 76, and she had surgery for pancreatic cancer in December of 2010. But she kept performing until her doctors advised her to stop. Her last performance was at ELTON JOHN's annual AIDS fundraiser last November. A ton of celebrities have been Tweeting their support. Meanwhile, Beyoncé and Jay-Z just happened to be performing in Aretha's hometown of Detroit the other night, and they dedicated their show to her. We loved here in this scene from 1980 during The Blues Brothers movie. Wishing the best to the Queen of Soul!
