Last year Madonna revealed Instagram asked her to ease up on posting racy photos to her account – but that hasn't stopped the singer from posing in her underwear for her fans.

Madonna wrote, "Today I decided to sing in my underwear! No one seemed to mind! #loveyoufromtheinsideout #artforfreedom," along with a black-and-white photo of herself in her undies.

Madonna has previously uploaded photos of bondage cartoons and made headlines for showing off her armpit hair back in March.

We wonder if Instagram is going to send Madonna another strongly-worded letter.
