Legendary soul singer Bobby Womack died Friday at the age of 70.
Womack’s sister tells TMZ that he passed away in his sleep, but the cause of death is currently unknown.
Womack had struggled with drug addiction and health problems throughout his life including diabetes, colon cancer, and early signs of Alzheimer’s.
He began his career as a member of Curtis Womack and the Womack Brothers in the 1950s before the group eventually changed its name to the Valentinos. They released their single “It’s All Over Now,” which later became a No. 1 hit for the Rolling Stones.
Womack was also known for his solo hits including “If You Think You’re Lonely Now,” “That’s the Way I Feel About Cha,” and “Lookin’ for a Love.”
In 2009, he was inducted into the Rock and Roll Hall of Fame.
According to Rolling Stone, Womack was in the process of recording a new album called The Best Is Yet to Come featuring contributions from Stevie Wonder, Snoop Dogg, and Rod Stewart.
