Ruth-Ann Boyle (born 26 April 1970, Sunderland) is an English pop music singer who became famous during the 1990s. Together with producers Tim Kellett and Robin Taylor-Firth, she formed the British band Olive. The band became world famous with "You're Not Alone" in 1997.
In 1999 she sang lead vocals on tracks "Gravity of Love" and "Silence Must be Heard" on Enigma's album "The Screen Behind the Mirror", the former of which was also released as a single. She also performed guest-vocals for their 2003 album Voyageur.
Her first solo album 'What about Us?', produced by Michael Cretu of Enigma, was only released as a digital download via iTunes in 2007, quoting a lack of necessary project support and co-ordination to produce physical copies of the album.
