Sarah Harding (b. November 17 1981) is a singer in the all-girl group Girls Aloud from Manchester, England.

Whilst working as a waitress and barmaid in Manchester, she entered the UK talent-search show Popstars: The Rivals, and was picked as the final member of the five-piece group, Girls Aloud, that formed the female half of the eponymous 'rivals'.

Earlier in the year she had also entered FHM's 'High Street Honeys', the magazine's version of a national beauty contest, and her pictures appeared in the first ever top 100. She withdrew upon achieving success on Popstars. A year later she was voted one of the Top 30 sexiest women in the world by readers of the same magazine.

Her relationship with fellow Popstars contestant, Mikey Green, fell apart in 2003 and she has not had a long-term boyfriend since. Both of the singers admit to have on-going feelings for one and other, but the pair have no plans to reunite.
