American soul singer Isaac Hayes has died at the age of 65, police have said.
He was found dead at his home in Memphis, Tennessee, at about 13:00 local time (19:00 BST) on Sunday.
Hayes was reportedly found collapsed on the floor of a bedroom next to a treadmill that was still running.
Shelby country sheriff spokesman Steve Shular told the AFP news agency: "We don't believe there was any foul play.
"Based on the statement by family members that Mr Hayes had been treated of late from a number of medical issues, we believe that led to his death. There are no plans for an autopsy."
Hayes is best known for his soundtrack of the 1971 film Shaft, for which he picked up an Oscar, three Grammy Awards and a Golden Globe.
He also provided the voice for the South Park character Chef but quit in 2006 apparently due to disagreements over Scientology, a religion he had followed since the 1990s.
Badu used her opening monologue at Sunday night’s awards to tell Azalea, “what you doin' is definitely not rap.”
It's Monday morning and my bones hurt. I'm tired, hung-over, and there's a slight ringing in my ears.
