Next one on the list is… you knew this was coming, right? Miley Cyrus. We all love Miley and the controversy that seems to stick to her tighter than her ever favorite latex clothing. No, don’t pretend, we know you do. But even Cyrus sometimes goes too far. Case in point: her response to Sinead O’Connor’s open letter earlier this year, in which Miley mocked the singer’s past struggles with a mental disorder. Not classy, Miley. Luckily, Sinead dismissed the comment as just teenage shenanigans and the whole thing is now over and done with.
All is fair in love and war, but celebrity feuds don't count as either. Bad move, Miley.
