Lots of comments have been made recently on Miley's apparent weight gain - how the 18-year-old was sporting a supposed rounder face and a fuller figure.
Now Cyrus has fired back at her critics on Twitter.
The former Hannah Montana star posted a photo of an emaciated woman alongside the caption: 'By calling girls like me fat, this is what you’re doing to other people.'
She added: 'I love MYSELF & if you could say the same... 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.'
The star also shared a picture of Marilyn Monroe with the caption: 'Proof that you can be adored by thousands of men even when your thighs touch.'
Miley's friend Demi Lovato, who has in the past battled her own body image issues, tweeted in support of Miley.
She wrote: '@MileyCyrus god I love you. SO DO YOU!!! And whoever called you that has it coming. Miss you more than ever.'
Miley replied: 'I will destroy any one that calls you the F (fat) word. You have the SEXIIIESTTT curvyyyy body! I LOVE IT! Werk (work) those curves.'
