Demi Lovato may have hinted about the possibility of a third "Camp Rock" movie, J-14 reported.

The 22-year-old singer responded to a tweet from a fan who was suggesting that the actress and Joe Jonas should make another "Camp Rock" film. According to J-14, Lovato answered the fan by tagging Joe as well as Nick Jonas. She tweeted, "@joejonas & @nickjonas... Thoughts?"

In another tweet, the "Really Don't Care" singer even said that she has an idea for the third film, saying, "@kevinjonas you have to hear my idea.... Ask @Nickjonas & @joejonas... It's AMAZING. Miss and love you!"

Lovato's advocacy

Lovato is known for being an advocate for people who are struggling with eating disorders. According to a report from E! Online, the singer is now urging people "to rethink how people view those who are dealing with a debilitating illness like anorexia or bulimia."

Lovato was about 13 years old when she first started to develop an eating disorder, E! Online noted. During that time, nobody was open to discussing their body issues.

"I feel that if someone had admitted they had a problem, then I wouldn't have gone down that route myself. That's my goal in talking about my problems: I want to be the person for other girls that I needed to admire when I was looking for help and strength," Lovato said in an interview on "Cosmo on Campus" last year, as quoted by E! Online.

Now, the singer insists that mental illness can be isolating and the public's lack of education of it can cause more problems. "Having an eating disorder doesn't show 'strength.' Strength is when are able to overcome your demons after being sick and tired for so long. There's a wide misconception that anorexia and/or bulimia is a choice and you often hear people say things like 'why doesn't she just start eating?' Or even 'just stop throwing up'," Lovato explained, as reported by E! Online.

She continued, "Eating disorders do not discriminate. Neither does any other mental illness. These are deadly diseases that are taking lives daily. So please, let's be cautious of the words we use when discussing ED's and other mental illnesses."
