Miley Cyrus to perform on X-Factor: but warned to keep it clean

Miley Cyrus has been warned to keep it clean when she performs on 'The X Factor'.

The 'We Can't Stop' hitmaker shocked viewers with her racy performance at the MTV Video Music Awards last month and while producers are keen to capitalise on the publicity, they don't want her to be as "raunchy" on a family how.
