'X Factor' Britney song choices revealed

This week's X Factor will see the five remaining acts sing Britney Spears hits in honour of the US star's guest appearance on the show.

All the hopefuls will perform a Britney song along with an unknown 'American' track.

In her first live UK performance in five years, the pop princess will sing her comeback track 'Womanizer'. Miley Cyrus will also perform her single '7 Things'.

Eoghan Quigg, the last contestant in the boys category, will tackle the popstar's early hit 'Sometimes', while over-25s hopeful Ruth Lorenzo is working on her own interpretation of Britney's Joan Jett cover 'I Love Rock 'n' Roll'.

In Cheryl Cole's girls section, Alexandra Burke will sing 'Toxic' backed by 14 scantily-clad dancers, with Diana Vickers performing 'I'm Not A Girl, Not Yet A Woman' from the album Britney.

The X Factor airs at 7.35pm and 10.15pm tomorrow on ITV1.
