He told the Daily Star newspaper: ''Britney was nice and said hello to me, but those stars have such a massive number of people it's daft.
''Staff on the show were saying to her entourage, 'I'm just going to stick a bit of tape on this microphone, is that OK?' when I was setting up. I was going: 'Just f***ing stick it on there.'
''They should let people be who they want to be, not turn them into some superstar.''
Jake is nominated for the Barclay Card Mercury Prize tonight (30.10.13), but says he's not interested if he wins or not.

The indie star also says people from his hometown of Nottingham in England's Midlands have a skewed idea of what being in the music industry is like.
