@MileyCyrus: "@ChrisMcMillan bun testing."
Responding to fans' criticism over the proposed new style, the 19-year-old posted: "If you don't have something nice to say don't say anything at all. My hair is attached to my head no one else's and it's going bye bye."
Returning to the website a few hours later, she proved she had gone through with the drastic cut by uploading several shots of her new look, a platinum blonde pixie style, cropped close to her head on one side.
She further posted: "Never felt more me in my whole life."
