On stage vomiting, why?

Is this a new trend or what? Bieber first, and Gaga said what the heck, lets do this!

Gaga: "I'm throwing up, and this guy is dancing..." thats what she might be thinking 

Let it all out soldier...its okay, take your time!!

Superstars are vomiting on stage these days in front of their fans. Lady Gaga during her performance in Barcelona gig showed everybody what she had for lunch...eeeeewwww!!!! Poker Face or PUKE Face, I dont know which one you guys prefer, but come on now.... I guess somethings you just cant control? Really? She tweeted where she had lunch before her performance, okay....With all the great energy she brings to the stage like we all know, shouldn't she be more careful eating "heavy" before a concert? Or maybe its a trend now a days, because apparently your boy Justin Bieber also puked on stage in Arizona last week. Did he had a fever, no, he laughed about it and said "I had milk before stage", oh momma...... maybe he can get away with it since he's still a kid. Who's next?
