Lady Gaga throws up on stage, still hits routine

We sincerely hope this vomiting-during-a-live-performance bug isn't catching.

Following Justin Bieber's milk-induced nausea, Lady Gaga's proved that she, too, can toss her cookies in front of a paying crowd without missing a beat.

The Mother Monster tweeted a link to a video that shows her performing during a tour stop in Barcelona, noting that she "was praying nobody saw but actually its quite a good laugh if u need one!"

As she makes her way down a staircase to the sound of "Edge of Glory," she has to stop short a few times to turn her back to the audience, in an attempt to hurl in semi-privacy. (We also would like to give kudos to the dancer standing right next to her for completely keeping his composure and his choreography.)

But after doubling over a few times, Gaga kept the show going. She tweeted Monday morning, "I still hit my routine mom!! :) Thank goodness for the Dorchester...i need some tea, i think i just cried a little watching that."
