Cyrus has been hitting red carpets looking thinner and in better shape recently and she credits a gluten-free diet and pilates for her weight loss.
After tweeting a photo on Sunday of herself sniffing the inside of a Carl's Jr. bag, she took some heat though.
She tweeted: "I can't eat it. So I'm just gonna smell the shittttt out of it! My mouth is LITERALLY watering."
Naturally, that turned everyone's thoughts to anorexia, because if Miley can't eat fast food, she must be starving herself, right?
The haters lit up the Twitterverse, saying that she's way too thin and must have an eating disorder.
Cyrus shot down the hate quickly, tweeting that she has a gluten allergy: "For everyone calling me anorexic I have a gluten and lactose allergy. It's not about weight it's about health. Gluten is crapppp anyway!"
She supported her slam on the anorexia rumors by tweeting her sister, Noah, writing: "@noahcyrus love u noie! U saw how much I ate today at Easter lunch but all of it was healthy and even more fulfilling! Health is happiness!"
Will Smith seemed to be in Miley's corner too, as she retweeted his thoughts on not being able to please everyone: "Skinny = anorexic , thick = obese , virgin = too good , non-virgin = slut , friendly = fake , quiet = rude. You can never please society."
He's not wrong.
Back in the fall, Miley took major heat because of her weight gain.
She had to address those criticizing her, using Twitter again to set people straight: "By calling girls like me fat, this is what you're doing to other people" (she included a photo of a woman with an eating disorder), adding, "I love MYSELF & if you could say the same you wouldn't be sitting on your computer trying to hurt others."
She also posted a photo of Marilyn Monroe and wrote: "Proof that you can be adored by thousands of men even when your thighs touch."
Demi Lovato threw Cyrus some love in a tweet that read: "@MileyCyrus god I love you. SO DO YOU!!! And whoever called you that has it coming."
It was a girl power moment, as Miley tweeted to Demi: "I will destroy any one that ever calls you the F word. You have the SEXIIIESTTT curvyyyy body! I LOVE IT!"
Miley ended her rant against the haters by tweeting: "I don't wanna be shaped like a girl I LOVE being shaped like a WOMAN & trust me ladies your man won't mind either."
And now that Miley is thinner and in better shape, she's got to face a whole new crop of haters?
Celebs just can't win sometimes.
