Rah rah, oh la la! Lady Gaga has been hospitalized for altitude sickness following her concert in Denver. She shared the news of her hospitalization on Instagram (where else?) with the caption "Altitude sickness is no Joke! #hitThatHospitalShit #artRaveDenver many true ravers crowd tonight."

Altitude sickness in the mile high city of Denver is no surprise, not to mention when it's coupled with lots of singing, dancing and general craziness on stage. Her next concert, this Saturday in Seattle, is still scheduled to go on. Little monsters everywhere are wishing her a speedy recovery.
