What is it with celebs and vomiting at the moment?
The 'Born this Way' singer was performing the Barcelona leg of her world tour when the incident occurred.
The thirty second video, shot by a fan, sees Lady Gaga attempt to begin her hit 'Edge of Glory'.

However, Gaga's stomach had other plans leading to the singer leaning over the edge of the raised platform she was perfroming on and throwing up.
We just hope no one was standing directly below her.
Much like Bieber, professional Gaga then tried to carry on with the performance.
Unfortunately this wasn't to be as after just a few energetic dance moves, Gaga was forced to turn around to throw up yet again.
Gaga vomitted a total of four times during the video, leaving her back up dancer to take centre stage in a bid to pull focus from the ill singer.
This is not the first time that Lady Gaga has fallen sick on the tour after throwing up backstage in Romania.
The singer recently came under fire after gaining 25lbs with some people speculating that there was a baby Gaga on the way.
This bout of sickness probably won't help matters.
