Miley tweeted: 'Before Amanda Bynes… There was…' accompanied by a screengrab of what appears to be a fake Sinead Twitter account (handle: @vampyahslayah) which shows the singer asking for help.
The images are unashmedly pornographic in nature, showing the former child star in a series of overtly sexual poses, wearing next to nothing.
"In a number of pictures, she wears a tiny leotard that barely covers the lower part of her body, featuring a G-String in the back, and not much thicker strap in the front. In one shot, she leans against a wall with her hand while herself, in another , she pulls the front of the leotard so high that she exposes half her crotch".
How far is too far?
