Vanessa Hudgens is out there trying to promote her music, but she ran into some difficulty while performing one of her songs.
Vanessa was singing one of her songs at a concert when she put the mic down before the lyrics stopped(1:17).
All these 'stars' that find a need to lip sync are not musicians, they're dancers. It seems like they concentrate more on dancing than they do on singing right? You will never see this from musicians such as Alicia Keys, Rihanna and many more. Just sing live or don't sing at all!
