9. Britney Spears’ disastrous 2007 performance
Obviously 2007 was not a good year for Britney Spears. During her very public meltdown, she was in and out of drug rehabilitation facilities, shaved her head bald and exhibited plenty of bizarre behavior that kept the tabloids busy. It was also the year that she put on a VMA performance that she would like to forget. The pop star looked out of shape and almost emotionless during her lip-syncing, lackluster Gimmie More performance.
