Britney 'wanted at least $13m for X Factor spot'

Britney Spears demanded her 'X Factor' pay deal was higher than Jennifer Lopez's earnings for 'American Idol'.

The 'Toxic' singer eventually agreed to a $15m payment for one season of the US version of the Simon Cowell-fronted talent show, $3m more than the 'On The Floor' hitmaker gained for her first season on the rival programme.
