ViDEO: Lady Gaga Acting as Justin Bieber?!

Lady Gaga made a stop in Barcelona, Spain for her “Born This Way Ball” concert over the weekend. Not knowing that a vomit fest will soon ensue.

In a video making the rounds, the 26-year-old can be seen slinking down a staircase with her back to the audience during a performance of “Edge of Glory” in Barcelona. Then, as she makes her way across a stage plank toward a dancer, she abruptly throws up at least four times.

At one point, her backup dancer gently pats her on the back as she tries to hurl inconspicuously.

But you gotta give it to Mother Monster: Ever the pro, she barely missed a beat and continued with the performance.
