The music world is in mourning this week after the death of Grammy Award-winning singer Betty Wright, who passed away on Sunday morning at the age of 66.

Daily Mail reported that Wright’s death was confirmed by her niece, who took to Twitter to let the world know what happened.

“I just lost my aunt this morning…. and now my mood has changed…. sleep in peace aunty Betty Wright. Fly high angel,” she tweeted. “My auntie was a legend…. she helped me get my first paychecks singing background….. and I didn’t make it to see you this past week and that’s going to haunt me …. R.I.P. Betty Wright.”

Wright’s cause of death has not yet been announced at this time. Her passing comes days after her fellow singing legend Chaka Khan asked her fans to pray for the star last week.

“My beloved sister, Betty Wright is now in need of all your prayers [sic],” Khan tweeted. “‘Que Sera, Sera | Whatever Will Be, Will Be’ In Jesus Name We Pray for Sister Betty All My Love Chaka.”

Born in Miami, Florida, Wright was only 18 years-old when she shot to fame in 1971 with her hit song “Clean Up Woman.” She went on to win the Best Rhythm and Blues Song Grammy Award for her song “Where Is the Love.”

Later in her career, Wright served as Beyonce Knowles’ vocal coach. Beyonce sampled Wright’s song “Girls Can’t Do What the Guys Do” tune on her 2006 hit with Jay-Z, “Upgrade U.”

Wright was a mother of five children, but she was sadly predeceased by a son who was fatally shot back in 2005, and nobody was ever arrested for his murder. She is survived by her other four children.

Wright once famously turned down $1 million to perform in South Africa in 1981, showing that she was a woman who stuck by her convictions. She was able to work consistently in the music industry for decades, and she was once asked about her work with the new generation of music stars.

“‘I believe in legacy,” Wright said. “And I believe in making the radio sound better. If I gotta listen to it, I want it to sound good.”
