Cowell calls Christina Aguilera 'bad'

Simon Cowell has called Christina Aguilera's super Bowl performance 'bad'.

During an interview with Fox News, Cowell was asked about the performance and said: 'Well I just heard it then and it sounded like 100,000 people in a stadium had just sat on a cat.'

When the clip began playing again, he said: 'No, don't play me any more!'

He added: 'Well look, obviously, she is regretting it now. She must be. I'm listening to it here in London and it didn't sound great to me. But to mess the words up? Not great.

'But I always say this, this is what happens when you perform in front of an audience- even someone as experienced as Christina. You can get it wrong. It was bad.'
