Demi's big break on Camp Rock

In 2008, Demi starred in the Disney original TV movie 'Camp Rock' as the network looked to capitalise on the popularity of the hit film 'High School Musical'.

Lovato played wannabe singer Mitchie Torres in the film - which also featured the Jonas brothers and proved popular with viewers.

She later joked that the cast should reunite for an "R-rated" version now because the original fans would be old enough to watch it.
