"Surely she throws up here and there," Lovato wrote.
Demi Lovato opened up about her battle with bulimia while showing off her stretch marks in an empowering Instagram post on Christmas Eve.
"I used to genuinely believe recovery from an eating disorder wasn’t real," the "Sorry Not Sorry" singer wrote. "That everyone was faking or secretly relapsing behind closed doors."
"I'm so grateful that I can honestly say for the first time in my life - my dietitian looked at me and said 'This is what eating disorder recovery looks like,'" she said alongside a series of Instagram versus reality photos.
