Never did we think Lady Gaga would take stage performance tips from Justin Bieber, but it appears the two pop powerhouses are at least ailing from the same stomach bug.

While performing her hit "The Edge of Glory" during a show in Barcelona, Spain, Gaga vomited three times behind one of her dancers.

Unlike the Biebs, who jokingly blamed his case of the pukes last week on bad milk, Gaga didn't give an explanation but instead Tweeted a humorous aside and a link to the video to her 30 million Twitter followers.

"Was praying nobody saw but actually its quite a good laugh if u need one! Check out Lady PukeGA doing Swan "Vomit" Lake," she quipped. "I still hit my routine mom!! :) Thank goodness for the Dorchester...i need some tea, i think i just cried a little watching that."

Gaga was in London the following day and apparently feeling well enough to promote her Fame perfume at Harrods, but was met by a series of boos from fans when she appeared an hour late and refused photo ops.
