Cyrus denies going under the knife
Miley Cyrus has hit out at reports she's had breast enlargement surgery.
The former Disney star sparked speculation when she attended a red carpet bash in Los Angeles on Sunday.
Miley's voluptuous appearance in a plunging Roberto Cavalli dress led to reports that she'd had plastic surgery at the age of just 19.
But the ex-Hannah Montana actress has tweeted: "Thank you for the compliment but these babies are all mine."
She added: "I wish they'd realise you don't have to be fake to be beautiful!"
Tattooed star Miley, who is set to voice the role of a teenage vampire in new animation Hotel Transylvania, was joined by her boyfriend, Aussie actor Liam Hemsworth, at the CNN Heroes tribute event on Sunday.
