Fergie should be more careful with the shoes she wears. Also she should move less or at least rehearsal more her moves. Otherwise she will collapse every time while on stage, as she did recently during a Kansas City concert.
The Black Eyed Peas singer, dressed in her signature silver and chrome bodysuit, fell during “Let’s Get It Started” song, but she got straight back up as if that was part of the dance routine. This time she only fell to her knees, but next time she might not be that lucky. As you can see, being a singer is not only about having a good voice, it’s also about being an acrobat.
