She has kind of asked for it. She has gotten so pretentious as of late that it's kind of turned people off.
However people are having fun with her in this 'mediocre state' because 2 years ago she was truly a dominant force to be reckoned with. No one was touching her or moving her. So since she's somewhat down, why not pounce on that ass? Everyone else does it to Rihanna, Beyonce, etc.
