After a controversial performance with Robin Thicke at the MTV VMAs, interest in the star has risen considerably.
A source told The Sun: "X Factor never miss an opportunity to exploit a situation, so the moment Miley put on THAT routine at the VMAs, producers put the wheels in motion to try to sign her up."
However, bosses have been explicitly clear in their negotiations stating that any performance by Miley would need to be calm and appropriate for the public.
