Girls Aloud singer Sarah Harding has died due to breast cancer. She was 39.

Harding's mother Marie confirmed the tragic news in an Instagram post on her daughter's account Sunday morning.

"It's with deep heartbreak that today I'm sharing the news that my beautiful daughter Sarah has sadly passed away. Many of you will know of Sarah's battle with cancer and that she fought so strongly from her diagnosis until her last day. She slipped away peacefully this morning," her mom confirmed.

"I'd like to thank everyone for their kind support over the past year. It meant the world to Sarah and it gave her great strength and comfort to know she was loved. I know she won't want to be remembered for her fight against this terrible disease – she was a bright shining star and I hope that's how she can be remembered instead," her mother's statement continued.

Harding first revealed her cancer diagnosis in August 2020 before further detailing her experience in her memoir, Hear Me Out.

"I'd been playing my guitar a lot, and I thought the strap had probably irritated an area around my breast," she explained in the book.

In addition to her work with the Out of Control girl group, Harding also released music as a solo artist. Her single, "Wear It Like a Crown," topped the iTunes charts in 2021 with proceeds being donated to the Christie NHS Foundation where she received her treatment, the English singer wrote on Instagram.

"What I'd really like to do is to see everyone — all my friends, all together. One last time. Then I'd throw a great big f— off party as a way to say thank you and goodbye," Harding noted in her memoir. "Wouldn't that be amazing?"
