Demi Lovato may have said that she hates the twerking trend while her pal Miley Cyrus twerks till she can't twerk no more. But the 'X Factor' judge is not above getting her twerk on every once in a while. She twerked up on her boss Simon Cowell during last week's episode.

Lovato decided to get turnt up when a contestant performed 'Baby Got Back.'

Looks like it was Si Co who got backed up on! Twerk, b---h.
