Shaznay Lewis was a member of the popular girl group All Saints (1996-2001 and 2006- 2009). She grew up listening to Bob Marley and Johnny Mathis. As a teenager, Lewis played three matches for Arsenal Ladies, a successful ladies' football team in London, UK. She returned to football in the 2002 hit movie Bend It Like Beckham in the role of the team captain and can be seen playing football in several training and match scenes.
Lewis had been entering singing contests since the age of 13. At a party, her friends introduced her to Ben Volpeliere-Pierrot of Curiosity Killed the Cat, who then took her to the Metamorphisis recording studios on All Saints Road in London and started doing backing vocals. It was there she met Melanie Blatt in 1993 and they proceeded to record together. Together with Simone Rainford they formed the group All Saints 18.104.22.168. which was later renamed All Saints. Soon after Rainford left the group, Nicole and Natalie Appleton joined.
Shaznay was the most active songwriter of the All Saints and was responsible for writing most of their songs including many hits. In 2001, she won the Ivor Novello Award for Most Performed Work for her No. 1 single “Pure Shores.” On November 14, 2004, Shaznay was involved in the Band-Aid 20 re-recording of "Do They Know It's Christmas.”
Also in 2004, Shaznay married dancer Christian "Storm" Horsfall. They had their first child, Tyler-Xaine, in February 2006. Later that year, it was announced that All Saints had reformed with a new recording contract and were recording a new album. All Saints' comeback began well, with their single, "Rock Steady,” reaching No. 3 in the UK charts, quickly followed with the release of their comeback album, Studio 1. The album peaked at No. 40 in the UK album charts.
In recent years, Shaznay has focused on writing and collaborating with other writers, producers, and artists. This has resulted in significant success with UK artists Westlife, Stooshe, Little Mix, Cock n Bull Kid, and others. She works regularly with top UK producers Futurecut and Richard ‘Biff’ Stannard.
