JLS: 'X Factor' needs 'best judge in world' Cowell

JLS think 'The X Factor' "needs" Simon Cowell to return to the judging panel.

The 'Hottest Girl in the World' hitmakers – who finished second on the competition in 2008 – believe the music mogul should return to the ITV1 programme because he is the "best judge in the world", although they admit it will be "very difficult" because he has such a busy schedule.
