Demi Lovato Defends ‘Healthy’ Figure and Dismisses Haters

After getting treatment for bulimia, Demi Lovato has been sporting a healthier figure, but some criticized the 19-year-old for her weight after appearing at the 2011 MTV Video Music Awards. Despite their negative words, the singer is not letting the haters get the best of her.

"I've gained weight. Get over it," she tweeted last night. "That's what happens when you get out of treatment for AN EATING DISORDER."

Lovato subsequently deleted the message, but added: "Guess what? I'm healthy and happy, and if you're hating on my weight you obviously aren't. : ) #UNBROKEN."

The 'Skyscraper' singer wore a curve-hugging mini-dress to the VMAs where she presented the award for Best Collaboration with Chord Overstreet. After taking to Twitter to fight back against critics, actress Ashley Greene, sent Lovato a supportive message, reminding the former 'Sonny With a Chance' star that she's "beautiful."

"This is why you're my friend," Lovato replied to the 'Twilight' star. "Thank you girl." It looks like Joe Jonas' exes are getting along just fine.

In October 2010, Lovato entered a treatment facility to address her physical and emotional issues. She left the center in January and has since released her chart-topping single, 'Skyscraper,' and recorded her third full-length album, 'Unbroken,' which is set to drop on Sept. 20.
