Poor Lady Gaga - life is tough at the top, especially when you're up in the clouds. The Applause singer got struck down with altitude sickness during a recent flight from Denver to Seattle.
Lady Gaga posted a sick selfie, wearing an oxygen mask covering her mouth, and captioned the picture: "Altitude Sickness is no Joke! #artRaveDenver many true ravers crowd tonight."
Gaga struggled with the mile-high altitude after arriving in Denver as part of her artRave: The ARTPOP Ball world tour.
We've got to hand it to the worldwide popstar, she still managed to keep her Bambi eyelashes on.
Get well soon, Lady Gaga.
