We are all aware of her previous drunk act, where she stumbled through her songs and messing up her lyrics. Even winning the grammy didn’t improve her performance, instead it got worse.

Recorded on video while singing her famous hit song Rehab, she punches a fan! Not sure what made her do it and what the fan said to her, but still, it is pretty a shameful act. I could smell a lawsuit coming her way.

I’m these images will be in my head whenever I hear she goes “No No No” on the radio.
