Beyoncé just stopped the show before it began!
Ch-ch-check out the AH-Mazing opening performance (above)!
Britney is such a trendsetter!
After a guy waltzed on into the Kansas City auditions proclaiming to be better than Chris Brown, he showed them all right!
And Demi used to be on Barney!
It was so bad, they each stood up and just WALKED. OFF. THE. SET!
Wow!! We kinda feel bad for the guy, but then again… turning your back to the judges is a lil' rude!
