Dannii: 'We're scared of Simon'

Dannii Minogue is "scared" of Simon Cowell.

The Australian-born 'X Factor' judge - who is mentoring Matt Cardle, Aiden Grimshaw and Paije Richardson in this year's competition - admitted she feels threatened by the music mogul's boyband One Direction, and is also keen to ensure Cheryl Cole doesn't get a "hat-trick" after winning the show for the past two years.
