Soul singer Betty Wright is dead at 66 years old.

Wright’s niece announced her passing on Sunday morning.

“I just lost my aunt this morning…. and now my mood has changed…. sleep in peace aunty Betty Wright,” she tweeted. “Fly high angel.”

Wright died from cancer, according to Billboard. A week before her death, fellow songstress Chaka Khan asked her Twitter followers to pray for the singer.

Wright’s career started when she scored her first record deal at just 12 years old, according to People. Her first album My First Time Around was released when she was 15 and produced her first top 40 track "Girls Can't Do What the Guys Do." Her best-known song “Clean Up Woman,” was released in 1971, when she was only 18 years old. The song was later certified gold by the Recording Industry Association of America, People reported.

Five years later, Wright won her only Grammy award for her song “Where Is The Love?” She collaborated with artists across genres including Gloria Estefan, Bobby Caldwell and Snoop Dogg. Her music has been sampled by multiple artists including Mary J. Blige, SWV and Chance the Rapper.

In the early aughts, she appeared on Diddy’s show Making the Band as a vocal coach. She also coached Beyoncé, who later sampled one of her songs for her 2006 track “Upgrade U.” Other Wright mentees include Jennifer Lopez and Joss Stone. She was happy to pour into the next generation of music. Wright’s last album was 2011’s Betty Wright: The Movie, a joint project she released with The Roots.

"I believe in legacy," Wright told NPR in 2011. "And I believe in making the radio sound better. If I gotta listen to it, I want it to sound good. So I'm tired of people disturbing the peace, getting on the radio and sounding a hot mess. If I can tell what the note really is, why let them go to the note they think it is? I've got that mama vibe. I don't look at it with an ego."

In April, TV One dedicated an episode of Unsung to Wright’s career. Rapper Lil Wayne appeared on the show and described how Wright’s song “Tonight is the Night” resonated with him during his youth.

“There’s eras of the song in my life, the first is being in the backseat of a car. Your mom’s singing it and you’re singing right along with her,” Weezy said, according to People. The “Lollipop” rapper was also featured on Betty Wright: The Movie.

“The second is you’re riding in that car alone and now you find those words meaning something totally different than what they meant when you were sitting in that backseat.”

Funeral arrangements have not yet been announced.
