The legendary singer was forced to perform sitting down after twisting her ankle in a hotel bathroom on Friday night.
She was brought into the studio in a wheelchair to pre-record her performance of '(There's) Always Something There to Remind Me' on Saturday (October 20) after initially refusing medical attention, insisting that the show must go on.
"Dionne had an accident at the hotel and really hurt her ankle. She came to the studio in a wheelchair and everyone was really worried for her," a source told The Sun.
"She should have probably been in hospital getting it checked out. But she has not been in the business for decades because she flakes on people.
"She's a genuine pro and just grabbed the floor manager's arm, hobbled on to the stage, sat down and got on with it. She even joked that when her ankle gets better she's going to come back on and give us all a dance."
