Lady Gaga unfortunately got altitude sickness when she was performing in Denver, Colorado this past Wednesday!
She was taken to the hospital late Wednesday to recover. Don't worry, though, she was healthy enough to take a selfie with her oxygen mask!

So, Gaga fans, despite her "hospital scare", she still seems to be the same old Lady Gaga! And we love her for that.
Just make sure that you guys are safe if you ever go to an altitude you're not used to!
Stay healthy, Lady Gaga!
