Rebecca Loos has confessed that she is confident about her chances of winning X Factor: Battle of the Stars.

David Beckham's former PA, who has already appeared in several reality TV shows, will be paired with James Hewitt for the series.

"We are both fiercely competitive and feel there's no point taking part in something like this unless you want to win, and we see ourselves winning," Loos told the Sunday Mail.

Hewitt added, "I hope our rapport translates to the live studio audience and the viewers at home. I think together we've got the whole package - the singing, the looks, the fun."

The show begins tomorrow at 9pm on ITV1.
