A week after Justin Bieber horked a quart of (ahem) “milk” on stage at a concert, here’s Lady Gaga blowing chunks in the middle of a concert. Oh Gaga, is there no one you won’t rip-off I mean artistically borrow from? Although I do have to give her credit for working it into the choreography. “All right Gaga, now, we turn, pivot, bob, barf, bob, barf, sashay and then big jazz hands! No no no, you were off on the second yak. Take it from the top people! And can we get some more ipecac for Gaga?”
