Demi Lovato has hit out at critics who are chastising her for gaining weight, insisting they need to "get over it".
The teenage actress/singer underwent three months of treatment for a series of emotional issues, including an eating disorder, earlier this year (11).
Lovato has since overcome her problems and was snapped with a fuller figure in a silver mini-dress at Sunday's (28Aug11) MTV Video Music Awards.
The Camp Rock star has been the victim of cruel online taunts about her curvy new physique, but she has now hit back, insisting she's "healthy and happy" since piling on the pounds.
In a series of posts on her Twitter.com page, she writes, "I've gained weight. Get over it. That's what happens when you get out of treatment for AN EATING DISORDER... Guess what, I'm healthy and happy, and if you're hating on my weight you obviously aren't."
