The "Born This Way" singer was performing "Edge of Glory" for a crowd in Barcelona when she began to be sick.

Like Bieber, Gaga didn't let a little sickness slow her down. She jumped back in and continued the song without missing a beat.

While milk is to blame for JB's stomach stunt, Gaga didn't reveal what made her lose her lunch.

She did, however, take the situation in stride, tweeting, "Was praying nobody saw but actually its quite a good laugh if u need one! Check out Lady PukeGA doing Swan 'Vomit' Lake."

The singer even included a link so her Little Monsters could watch the performance gone awry. How sweet!
