The 21-year-old singer said she still avoids watching her episodes on television shows because of her eating disorder, reported People magazine.
"It is still hard being in front of the camera when you have suffered from eating disorders, and I still don't watch my episodes. It is hard," Lovato said.
"I think ultimately my main thing is singing. Maybe movies once in a while, if the right role comes along," she added.
Lovato has a new book out called 'Staying Strong: 365 Days a Year', in which she describes coming to terms with her illness.
