Holy sh*t - get your earplugs ready. We love us some Fergie but what the hell happened last night?!

The Black Eyed Peas diva put down some crazy jazzy vocal strains with the National Anthem at the NBA All-Star game and basically NO ONE liked it ... probably not even her!

Whose idea was it to arrange the song this way?! Fergie could barely hit half the notes and the players' faces, the crowds' faces were left stunned, shocked, shooketh! Hear and see for yourself ... What do YOU think?
