An independent doctor is to review the treatment of US soul legend Etta James, after her son raised fears over the care given by her live-in doctor.
The attorney for James's son Donto told the judge Dr Elaine James had carried out a procedure to insert feeding tubes that should only be done in hospital.
Mr James has alleged his mother could be in "very serious danger".
James, 72, known for her hit At Last, has dementia and is being treated for leukaemia and associated problems.
Dr James, who is not related to the family, told the Associated Press new agency she welcomed the independent review.
"He can have 10 examiners, he can have 20 physicians to come in that house to perform the duties I do," she said.
"I have a list of 23 medical sub-specialties that I have had to treat her for. She is not an easy patient."
In January the singer's husband, Artis Mills, was given permission by the judge to use some of her savings to pay for her health care.
Mr Mills claimed she had become too sick to manage her own money.
Mr Mills has also challenged a claim by Donto James that his mother gave him power of attorney.
The singer has been out of the public eye since January last year when she was admitted to hospital after suffering from various ailments, including a blood infection.
She became ill while in a clinic for treatment to an addiction to painkillers and other medicines.
James is the winner of four Grammy awards and was inducted into the Rock & Roll Hall of Fame in 1993.
In the 2008 film Cadillac Records, she was portrayed by the singer Beyonce Knowles.
