The 42-year-old pop princess recently performed her new single, Get Outta My Way, on the US show but isn't sure whether she would like to be a contestant.
Speaking to ET, she said: 'I love these shows. I think they do amazing work. I can't imagine going through that myself. It looks like torture... I would [be] petrified doing this type of show; I really, really would.'
She added: 'Part of me would love the challenge. What an amazing opportunity to work with incredible dancers, choreographers... that is very enticing. So, maybe one day.'
