Following in the undesirable footsteps of Justin Bieber, pop superstar Lady GaGa couldn't seem to keep down her dinner and made the stage her throw up bag, while performing at the latest stop of her 'Born This Way Ball' tour in Barcelona.
However, an even bigger issue from some fans and music critics, was that the incident revealed that the pop superstar was lip-syncing. Something that she claimed she had never done and would never do during her 2010 concert special for HBO. Busted!
