Madonna has hit back at social media's censorship rules today by posting a picture of herself naked on Instagram with just her nipples covered.
The 56-year-old singer posted the black and white image along with the caption "Why is it ok to show ass but not breasts? Drowning in the hypocrisy of social media".
It is believed the singer's picture is in response to alleged reports that the photo sharing site had previously removed an image of her posing fully topless.
Instagram's policy states that "users found sharing nudity or mature content will be disabled and your access to Instagram may be discontinued".
