Legendary soul singer Bobby Womack died Friday at the age of 70.

According to TMZ, Womack passed away in his sleep, but the cause of death is currently unknown. He has overcome cancer in the past but it's not known yet if his death was related to his past health conditions or not.

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.

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.

Rest in Peace Bobby Womack.
