Lady Gaga Vomits On Stage Lady Gaga's making herself sick. Last week, days after Justin Bieber puked during one of his concerts, Gaga vomited on stage in Barcelona, bending over a barrier to throw up multiple times while performing "Edge of Glory."

Gaga's health has been a subject of debate for the past month. She recently revealed her 25-pound weight gain and launched a "Body Revolution" movement online to fight criticism of all figures, famous or not. RELATED: Gaga's Response to Weight Critics
