Another Pop Puker (VIDEO)

Lady Gaga followed in Justin Bieber's footsteps during a concert in Barcelona, Spain last weekend when she tossed her cookies not once, not twice, but three times!

Gaga later tweeted, "Was praying nobody saw but actually its quite a good laugh if u need one! Check out Lady PukeGA doing Swan 'Vomit' Lake."

She added, "I still hit my routine mom!! :) Thank goodness for the Dorchester...i need some tea ,i think i just cried a little watching that."

Unfortunately for her, and fortunately for us, we've got video!
