We don't know what they're putting in the water down at The X Factor, but their contestants don't half love a spat. Whether it's One Direction's Louis Tomlinson kicking off with The Wanted and Nick Grimshaw, James Arthur making his feelings on Kingsland Road clear or Steve Brookstein having a go at everyone ever, they just can't help getting all sassy on us.
And now 2010 winner Matt Cardle's REIGNITED his feud with last year's champ James Arthur, claiming he's an 'angry person'. Uh oh.
