Girls Aloud are a British girl group that were created on the ITV1 talent show Popstars: The Rivals in 2002. The group, consisting of Cheryl Cole, Nadine Coyle, Sarah Harding, Nicola Roberts, and Kimberley Walsh, have been successful in achieving a string of 20 consecutive UK Top 10 singles (including four number ones), two UK number one albums, and having been nominated for four BRIT Awards, winning Best Single in 2009 for The Promise.
In March 2013, just a few hours after having performed their final concert at Echo Arena Liverpool, the five announced and confirmed their breakup on Twitter.

In August 2020, Sarah Harding announced that she had been diagnosed with an aggressive form of breast cancer and that it had now spread to the rest of her body. In early 2021, doctors revealed she would not see another christmas and on the morning of 5th September 2021 she passed away peacefully.

The group reformed as a 4 piece in November 2023 to announce a 2024 UK Arena tour.
