Aretha is very full of Aretha. She has the right to some pride, but she doesn't live in reality. Her voice is going fast and she doesn't have to be so damn nasty (and she is quite rude). She'd be lucky to have Audra play her. My guess is Aretha prefers someone to lipsync, as she originally wanted Halle Berry. Aretha doesn't want anyone overshadowing her vocals, or taking the focus off Aretha.
