With five successful years as Ginger Spice firmly under her belt, Geri Halliwell knows all about the world of music.
And the 37-year-old is set to share her wisdom in her new role as a guest judge on this year's X Factor.
The first celebrity to stand in for Dannii Minogue - who is expecting her first child in July - Geri will join Simon Cowell, Cheryl Cole and Louis Walsh on the popular reality show.
And it's not the first time the glamorous star has used her experience to help hopeful singers.
Geri was on the panel for PopStars: the Rivals - the show that discovered Cheryl's band Girls Aloud.
Other stars lined up to appear on the X Factor panel include Lily Allen and Charlotte Church.
