Sarah Louise Whatmore (born 5 July 1981) and raised in Walkden, in the City of Salford, England, is an English singer, best known from the British TV series Pop Idol.

Whatmore rose to fame in the first series of the British television show Pop Idol. Simon Fuller signed her to RCA Records including a world wide management deal with 19 Entertainment.

In 2002 and 2003 she released two singles "When I Lost You" and "Automatic" respectively which both reached the Top 20 in the UK Singles Chart. Whatmore was writing for fellow Pop Idol alumni, and spent time working on her debut album, 'Living Proof'.

A third single failed to materialise, and the release of 'Living Proof' was cancelled. Several recordings were leaked over the years, including "Close To Me" and "Don't Let Me Go".

Turning down the opportunity to become a backing singer for Kylie Minogue to concentrate on her own solo career, Whatmore spent the next five years honing her craft. During the years she wrote more than two hundred songs with various collaborators including Greg Fitzgerald and Peter John Vettese . Whatmore continued to record and write for herself as well as other musicians.
