Magician Paul Daniels and his wife and assistant Debbie McGee have become the first contestants to be voted off a celebrity version of the X Factor.

Other celebrities taking part include Lucy Benjamin, who starred as Lisa in EastEnders and James Hewitt and Rebecca Loos - both famous for newspaper kiss-and-tell stories.
