The previously whiter-than-white Disney star was treated in rehab for "emotional and physical issues" in November 2010, following her attack on a dancer while on tour with The Jonas Brothers.

Demi was admitted to the Michigan rehab facility shortly after she punched a female performer while travelling on tour.

Since leaving rehab in January 2011, the star has had the words stay strong' tattooed onto her wrists as an encouragement.
