Harris unveiled as 'X Factor' stage invader

Calvin Harris invaded the stage during John and Edward’s ‘X Factor’ performance last night.

The ‘Acceptable In The 80s’ hitmaker – who was due to appear on spin-off show ‘The Xtra Factor’ – was immediately ejected from the studios after the disturbance, which saw him interrupt the duo’s rendition of Queen classic ‘Under Pressure’ while clutching a pineapple on his head.
