Cheryl (singer) in the context of "Girls Aloud"

Girls Aloud are a British-Irish pop girl group that was created through the ITV talent show Popstars: The Rivals in 2002. The line up consisted of members Cheryl, Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh. In 2012, the group was named Britain's biggest selling girl group of the 21st century so far, with over 4.3 million singles sales and 4.0 million albums sold in the UK. The group achieved a string of twenty top-ten singles on the UK singles chart, including four number ones. They also achieved seven BPI certified albums, two of which debuted at number one on the UK Albums Chart. They have been nominated for five Brit Awards and won one of them, Best Single in 2009 for "The Promise".

The group's main musical style is pop, and they have also experimented with other sounds including electropop, dance-pop and dance-rock throughout their career. The group's collaborations with Brian Higgins and the production team Xenomania earned the group critical acclaim, because of an "innovative" approach to mainstream pop music. The group became one of the few British reality television acts to achieve continued success, amassing a fortune of £30 million by May 2010 (a value equivalent to £41 million in 2023). Guinness World Records listed them as the "Most Successful Reality TV Group" in the 2007 and 2011 edition. They also hold the record for "Most Consecutive Top Ten Entries in the UK by a Female Group" in the 2008 edition.
