Lady Gaga vomits on stage in Barcelona

Hopefully this isn't becoming a trend to show off how much of the consummate performer one is. Last week, Justin Bieber tossed his cookies on stage during a concert in Phoenix as part of his "Believe" tour. Now it's Lady Gaga's turn.

Above, during a show in Barcelona, Spain, you can see Gaga during "Edge of Glory." The best part? Both Gaga and the backup dancer totally roll with it.

Naturally, Gaga took to Twitter after the event:

• "Was praying nobody saw but actually its quite a good laugh if u need one! Check out Lady PukeGA doing Swan "Vomit" Lake."
• "I still hit my routine mom!! :) Thank goodness for the Dorchester...i need some tea ,i think i just cried a little watching that."
• "it WAS pretty metal. Belligerent throw up during sax solo amidst epic power ballad about glory atop medieval castle? #metal."

Heh. That was pretty metal.
