Christina Aguilera chose one of the most public places of all for her big embarrassing moment -- the Super Bowl. While singing the national anthem in February, the troubled songstress botched the lyrics during the live performance, viewed by more than 111 million people worldwide. Adding insult to injury, she fell off the stage at the Grammy's later that month! Clearly not done with her embarrassment streak, Aguilera was then arrested in March for public drunkenness.
