Nadine Coyle is an Irish singer, songwriter, actress, and model. She rose to fame in the early 2000s as a member of the girl group Girls Aloud. It was Louis Walsh who encouraged Nadine Coyle to enter Popstars: The Rivals, the second British series of the international Popstars franchise. The series' goal was to create two winning pop groups – a boy band and a girl group, each consisting of five members who would then partake in "a battle of the sexes" as they vie for the Christmas number one on the UK Singles Chart. Nadine Coyle joined Cheryl Tweedy, Sarah Harding, Nicola Roberts, and Kimberley Walsh to comprise the new girl group Girls Aloud, formed through the show by a public vote. The group's debut single "Sound of the Underground" peaked at number one on the UK Singles Chart, becoming the 2002 Christmas number one. Two of their albums have reached the top of the UK Albums Chart: their greatest hits album The Sound of Girls Aloud and 2008's Out of Control, both of which entered the chart at number one, with over one million copies of the former being sold. They also achieved seven certified albums and have been nominated for five Brit Awards, winning the 2009 Best Single for "The Promise". In November 2012 the band released their new single "Something New" which was also the official charity single for Children in Need. The group released their second greatest hits compilation Ten on 26 November 2012. Coyle and the group embarked on the Ten: The Hits Tour in February. After the tour's conclusion in March 2013, the group announced that they were disbanding. Going solo, Nadine signed a record deal with Virgin EMI Records in July 2017. She released the single "Go to Work" in September. As a member of Girls Aloud, Nadine Coyle appeared in the fly on the wall documentary Girls Aloud: Home Truths, the E4 documentary series Girls Aloud: Off the Record, and a one-off variety show entitled The Girls Aloud Party. Nadine has helped her bandmates endorse Barbie, KitKat, Nintendo DS, Samsung, Sunsilk and Pandora.
