Too much of anything can make you sick, Cheryl Cole warbled in her 2010 smash hit single, 'Fight for this Love'. But is it possible to have too much of Cheryl? Perhaps not in the UK, where the Geordie pop star is a national obsession; an obsession she feeds by regularly changing her job description and surname. And perhaps not for Jess McGuire.

As part of our You Don't Know Me series exploring unexpected and possibly unhealthy secret passions, writer/broadcaster Jess examines her own preoccupation with the artist variously known as Cheryl Tweedy, Cheryl Cole and Cheryl Fernandez-Versini. After shooting to fame in 2002 as a member of the reality-TV-assembled English pop group Girls Aloud, Cheryl has also become famous as a violent nightclub thug, spurned footballer’s wife, defiant solo artist, reality-TV judge, malaria survivor – and most recently, as a One Direction member-snatcher.
