She's never been one to shy away from controversy, that's for sure!

Madonna joined Instagram mere weeks ago, but already the Instagram Team is sending her letters requesting she tone down her sexy snapshots!

Clearly not embarassed about the slap on the wrist, Madge decided to upload the letter in full to her account, followed by a picture of herself in a black wig and cleavage-baring green leather dress. Yikes!

Some of the things on their no-no list? Sharing photos that aren't your own, sharing photos that show nudity or mature content, sharing photos of illegal content, and sharing photos that attack individuals or groups.

We think we know which violations she's guilty of...

It could have been her sweaty cleavage shot, or it could have been her booty pic, but something has made the app administrators angry!
