Hell hath no fury like a One Direction fan scorned. Remember what Caroline Flack went through?

It should come as no surprise then that One Direction's transatlantic teen army are threatening to mutiny over news that their curly-haired Casanova has shacked up with Taylor Swift. Strictly speaking, no one is good enough for Harry, but country pop superstar Taylor Swift is a real slap round the face because...erm...she's like, quite pretty and has had the audacity to go out with other men before Harry and most importantly is not ME.

This young lady has directed her jealous rage (and fairly impressive musical talents) into a video parodying the Taylor Swift song 'Trouble'. It includes the catchy refrain "She's gonna put him in her ex-boy pile."
