Nicole Marie Appleton-Gallagher (born 7 December 1974) is a Canadian pop singer and actress and a former member of All Saints. She was formerly a member of Appleton along with her older sister Natalie Appleton.
Appleton was born in Hamilton, Ontario to her Jewish British mother Mary and Canadian Jewish father, Ken. She has three older sisters; Lori, Lee, and Natalie. While growing up she lived in Toronto, New York City, and London.
In 1994 Appleton and her sister Natalie Appleton became the fourth member of the group All Saints, formed by Melanie Blatt and Shaznay Lewis. All Saints released their debut single "I Know Where It's At" in 1997 via London Records and reached number four on the UK Singles Chart. Their second single Never Ever was released in November 1997, and introduced the group to international success, reaching the top ten in several countries as well as peaking at number one in the United Kingdom and Australia. It sold over 1.2 million copies in the UK and was eventually certified double platinum by the British Phonographic Industry. In 1998 the group won two BRIT Awards for "Best British Single" and "Best British Video", both for Never Ever. They released their debut album All Saints in November 1997, it reached number two in the UK and was certified five times platinum by the BPI for sales of 1.5 million. The third single from the album was the double A-side "Under the Bridge / Lady Marmalade", which became their second UK number-one single. "Bootie Call", the fourth single, also went to number one, and the silver-certified "War of Nerves", the fifth and final release, peaked at number seven. The album achieved success in countries such as Australia, Canada and the United States, where All Saints was certified platinum by the RIAA for sales of one million and produced two top forty singles on the Billboard Hot 100: "I Know Where It's At" and "Never Ever".
In February 2000 they released the single "Pure Shores" for the soundtrack of the film The Beach (starring Leonardo DiCaprio). "Pure Shores" was their fourth number-one single in the UK and the second best-selling single of 2000, with 600,000 copies sold; it also became their first and only number-one single in Ireland and was a substantial hit across Europe and Australia. In October 2000, All Saints released the single "Black Coffee", which became their fifth and final number-one single in the UK, selling 200,000 copies. Also in 2000, Nicole and her sister both appeared in the film Honest. This preceded their second studio album, Saints & Sinners, which debuted at number one on the UK Albums Chart, eventually reaching double platinum certification in the UK for sales of 600,000 copies. The second and final single was "All Hooked Up" in January 2001, which peaked at number seven. In February 2001, All Saints announced that they were to take a break so that they "could clear the air between themselves". In November 2001, London Records released a greatest hits compilation entitled All Hits and disband.
In September 2002, Nicole and her sister Natalie launched themselves back onto the music scene, with their first single "Fantasy" written with Andy Hayman and Gareth Young reaching #2 in the UK Singles Chart. Their autobiography, Together, came out in October 2002. In 2003, they had two more hits with "Don't Worry" and "Everything Eventually" and the album, Everything's Eventual which went gold in the UK after just two months. They decided to sign a deal with Concept Music in late 2004 because of differences with their previous label, Polydor.
On 24 January 2006, it was announced that the band had reformed and signed a record deal with Parlophone. They subsequently began work on their third studio album, Studio 1. The first single, "Rock Steady" (released in November 2006), reached number three on the UK Singles Chart. Studio 1 entered the albums chart at number forty and sold 60,000 copies according to the BPI, being certified silver. A second single, "Chick Fit" failed to reach the top 200. The group discussed the reunion's failure in an interview with i-D magazine in 2012: "I don't think it was done for the right reasons... I know that I did it for the money. We got signed before we had even made music again, it wasn't like we felt we had something to give back to the world... we were given an opportunity and took it, without really thinking about it too hard". She also said she never felt comfortable with the success the band had and that "it was not necessarily the plan at the beginning; there was a lot of compromise involved".
