First Justin Bieber threw up on stage while performing and now Lady Gaga did the same thing in Barcelona yesterday. She was singing The Edge of Glory and mid-way through the song she lost her dinner. After the show she Tweeted, “Was praying nobody saw but actually its quite a good laugh if u need one! Check out Lady PukeGA doing Swan ‘Vomit’ Lake” Good thing she has a sense of humor about it. And just like Bieber, she went on with the show. You have to respect her for that.
