The 30-year-old singer is currently judging the UK version of The X Factor along with Tulisa Contostavlos, Louis Walsh and Gary Barlow after being given the job by music mogul Simon Cowell.
Speaking about Cowell, she said to UK newspaper Sunday Mirror: 'He calls me Lippy. He likes me because I have a smart mouth. I'm not afraid of him and I respect him.
'I'm actually not afraid of him in any way. We would be electric on the same judging panel - can you imagine? I love my panel. I love being on a panel with Gary and Louis and I love being on the panel with Tulisa - despite what people are saying.'
