Leave Britney alone!
Some crazy guy ran up on stage during the middle of Britney's "Piece of Me" concert in Las Vegas on Wednesday night. The man, who had been disorderly during the concert and asked to leave, was quickly taken out by security guards and back-up dancers. The scare was enough to halt the concert, and even cause Britney's knees to buckle when her security informed her on stage what was going on.
