She really needs to rest and take a much deserved break. She is being overworked. This is the worst performance I have seen from her, but I have to give her props for performing on the show when she was hospitalized just the night before. She also seemed to be having problems with her costume, and I'm not sure whether or not she was supposed to actually smash the window of the car.

I saw her in concert last month and she was great. She puts passion into each of her performances, and I feel like this one was missing that. But no one is perfect and we all have our bad days. After the Grammys she has 2 free weeks before her European tour begins. Hopefully she takes that time to eat, sleep and allow her body to rest mentally and physcially.
