Girls Aloud were a British girl group formed in 2002 on the talent show Popstars: The Rivals. Consisting of Cheryl Cole, Nadine Coyle, Sarah Harding, Nicola Roberts, and Kimberley Walsh, they achieved great success with 20 consecutive UK Top 10 singles (including four number ones) and two UK number one albums. They were nominated for four BRIT Awards and won Best Single in 2009 for "The Promise". In March 2013, shortly after their final concert, the group announced their breakup on Twitter.
In August 2020, Sarah Harding revealed she had been diagnosed with an aggressive form of breast cancer that had spread throughout her body. Despite doctors' prognosis that she would not see another Christmas, she fought bravely until September 5th, 2021 when she peacefully passed away.
