Miley Cyrus has defended her figure after she was accused of being fat.

The former 'Hannah Montana' star was criticised after sporting a new curvier shape but Miley - who is dating 'The Hunger Games' star Liam Hemsworth - has taken to twitter to hit back at her detractors.

Posting a picture of an emaciated woman whose ribs were visible, she wrote: "By calling girls like me fat, this is what you're doing to other people.

"I love MYSELF & If you could say the same you wouldn't be sitting on your computer trying to hurt others. (sic)"

Miley then tweeted a picture of curvaceous blonde bombshell Marilyn Monroe and wrote that men - including Liam - prefer curvy women.

She said: "Proof that you can be adored by thousands of men even when your thighs touch.

"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 ;) (sic)"

Miley's close pal 19-year-old Demi Lovato, who was treated for an eating disorder last year, supported her pal on the micro-blogging website.

She tweeted: "god I love you. SO DO YOU!!! And whoever called you that has it coming. ps SO proud of you for posting that! #curvesareBEAUTIFUL. (sic)"

Miley replied: "Amen. 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. (sic)"
