Lady Gaga vomits four times during performance in Spain

The show must go on. During a concert in Barcelona, Spain, on Saturday night, Lady Gaga vomited on stage not once, twice, but at least four times mid-performance … and she just kept on singing and dancing throughout the entire puke fest. The 26-year-old singer was right in the middle of "Edge of Glory" when, with her back to the crowd, she leaned over and hurled onto the stage. In a video posted of her first stomach-churning moment, her backup dancer stopped and put his hand on her shoulder to comfort Gaga, but she went right back into the song's choreography.

Gaga, who reportedly had been battling the flu, had a good sense of humor about it all after the video made the rounds online. "Was praying nobody saw but actually its quite a good laugh if u need one!" she tweeted along with the 27-second clip.

WARNING: The following video is not for the faint of stomach:

Gaga's vomit-a-thon comes just a week after Justin Bieber also got sick onstage while kicking off the first night of his "Believe" tour. And just like Gaga, he also didn't miss a step — although his voice could still be heard "singing" even though it was clear he was not. The two join a long list of performers who have been struck by nausea during a concert, including Rihanna, Katy Perry, and Kings of Leon singer Caleb Followill, although they all ran off the stage to get sick in private. In 2010, Taylor Momsen was so overcome by heat while performing that the leather-clad singer "almost threw up in the middle of the second song," she told BBC Radio 1. "I was spewing in my mouth and swallowing it back down and I kept turning around and singing."

Luckily for Gaga, she has three weeks off before her next Born This Way Ball gig in Mexico City. Let's hope she stocks up on Pepto Bismol!
