Lady Gaga was caught vomiting multiple times while on stage when performing “Edge Of Glory” in Barcelona over the weekend.

The singer was walking down some stairs, more slowly and less confidently than usual, when all of a sudden she turned to the edge of the stage and began to up-chuck. Her backup dancer tried to shield her from view.

Justin Bieber was filmed throwing up on stage last week, ABC wrote.

After briefly checking if the pop star was okay by patting her on her lower back, the dancer continued to perform as Gaga puked her brains out.

In between the vomit sessions, Gaga tried to dance as much as possible before she ultimately stormed out on the stage to continue to the rest of the song.

The video is proof that Mother Monster must be lip synching some of her songs as her vocals could be clearly heard while the vomit was hurling from her mouth.

Gaga’s stomach might have been in knots from the Spanish paella she ate earlier in the day.

She tweeted about the country’s cuisine:

“In SPAIN having the time of my life!!!!!! *eats Paella in the corner* I love it here so much, my view is beautiful I'm gon rock Barcelone!”

The pop star announced that she used to have a problem with bulimia; could it be that she’s still struggling with the disease?

After she was hounded for her 25-pound weight gain, which she attributed to eating Italian comfort foods like pasta and meatballs, the singer launched the “Body Revolution” on her website “Little Monsters,” so it’s unlikely that she’s suffering with a bout of bulimia again.

More likely than bulimia, Gaga could be hiding a pregnancy. She has been in a very public relationship with actor and model Taylor Kinney, so it wouldn’t be too surprising if she were pregnant with his child.

Instead of trying to cover it up, Lady Gaga tweeted about the sickening episode on the Barcelona stage:

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

She also said, “SPAIN, you took the p*** outta me. Thats some hard bodied pop stuff. I'll never forget tonight Barcelona. FOREVER"

Later she retweeted a post from a fan that said, “@Ladygaga was doing the monsterball puke introlude in real life.”

And she even wrote something to her mother, “I still hit my routine mom!! :) Thank goodness for the Dorchester...i need some tea ,i think i just cried a little watching that,” referring to getting sick on stage.

If it seems odd that Gaga would go out of her way to bring attention to such an act, maybe it’s because she’s trying to hide something bigger.
