It could be one of her latest fashion shockers, but we're pretty sure Lady Gaga didn't plan her latest oxygen mask accessory.
The Applause singer stunned fans when she posted this sicked selfie after being struck down with altitude sickness on tour in Denver.
Gaga, it seems, couldn't handle the mile-high altitude after arriving there as part of her artRave: The ARTPOP Ball world tour.
After the gig, the eccentric beauty shared this picture on Instagram, from her hospital bed wearing an oxygen mask. She wrote: "Altitude Sickness is no Joke! #artRaveDenver many true ravers crowd tonight."
Despite feeling under the weather, the fashion-conscious crooner still managed to keep her amazing eyelashes and full face of slap in place.
Get well soon, Lady Gaga.
