The Sun have reported that the model, 32, sold only around 3,000 copies of Free To Love Again.
The poor chart result came after she was booed while performing at Mayhem in Essex, where things got even more embarrassing for Katie when her backing track started to skip, showing that she wasn’t singing live.
A audience member told The Sun: ‘When she got on the stage the booing started and didn’t stop.’
‘It got a bit embarrassing when the track was skipping. Everyone then knew she was miming but she just carried on.’
