Everyone of us sometime needs to puke - even singers like Lady Gaga! But to do it in front of fans while performing, now that takes balls of steel! The Born This Way singer was performing 'Edge of Glory' in Barcelona as part of her 'Born This Way Ball' world tour when the incident occurred. Fan footage sees the star vomit at the back of the set, while a dancer notices and performs in front of her to obstruct the audience's view. After throwing up three times in a number of seconds, GaGa struts to the front of the stage to continue with the show. Check out the incident, HERE!
