No this is not part of the elaborate costuming in her new ArtRave tour, though the "Applause" singer manages to make even an oxygen mask look glam in this selfie posted August 6.
“Altitude Sickness is no Joke! #hitThatHospitalShit #artRaveDenver many true ravers crowd tonight,” Lady Gaga posted on Instagram with this pic after being hospitalized for the illness on a Denver tourstop Wednesday night.
She posted the selfie after performing in the Mile High City, where altitude sickness is apparently common.
The star seemed to be up and at 'em the next day--good news for fans hoping to catch her ArtRave: the ARTPOP Ball show at Rogers Arena on Saturday night (August 9): yesterday (August 7) she was well enough to post a pic of herself surrounded by naked men, announcing that a new "Eau de Gaga" would be coming out soon. (Miss Poker Face had to postpone her May show here due to illness.)
So we can expect Gagaloo to appear in her wild wigs, tentacle gowns, and seashell bras at the Ball on Saturday night, but no word if she will be wearing them with a breathing device.
