Madonna, Madonna, Madonna. The Queen of Pop is infamous for pushing envelopes and breaking rules, but not even the Material Girl herself is free from Instagram's fury. The 'Girl Gone Wild' singer was slapped with a violation notice from the photo sharing service, which she shared with her 152,000+ followers.

Madge posted a photo of the violation notice for her followers to see.

The notice warned against posting photos featuring “nudity or mature content” as well as against sharing photos that come from third parties.

"We value these guidelines, and believe that they will help keep Instagram a safe & fun place for everyone," the message says. "It is important to note that continuing to violate them may result in a disabled account, or discontinued access to Instagram, without warning."

It's not entirely clear which violation Madonna was being cited for, but she has posted cleavage and butt-centered shots. Still, those are tame compared to the photos Rihanna posts every 10 minutes!
