Blues singer Etta James, who has been suffering from chronic leukemia, is terminally ill, her doctor said.

Dr. Elaine James, who is unrelated to the singer and has been living with her since March 2010, is now asking James’ fans to pray for her.

Court documents show that James also suffers from dementia and kidney failure.

The 73-year-old entertainer, who is most famous for the hit song “At Last,” is now under the 24-hour care of Elaine James, who was hired by the singer’s husband, Artis Mills, in 2001.

In the 1960s and 1970s, James was in and out of rehab programs for a heroin addiction. In 1974, she spent 17 months in the hospital after she was arrested for drug possession and sentenced to drug treatment instead of prison time.
