The ArtRave has taken its toll on Lady Gaga. The Artpop star has been forced to postpone two dates on her new tour due to bronchitis. 

Last night, Mother Monster was set to hit the stage in Seattle, but tweeted her "deepest apologies" that she would postpone her ArtRave: The Artpop Ball show and an upcoming date in Vancouver this Friday. 

The singer added that famous Disney villain Ursula "took my mermaid voice." Which is sort of ironic considering Gaga dons an extremely Ursula-esque stage costume in the tour—complete with tentacles.

Gaga's the latest pop superstar to see her tour derailed due to ailment. Last month, Miley Cyrus postponed and rescheduled nine dates due to an "extreme allergic reaction to" an antibiotic. But let's hope that Gaga's sickness only affects these two shows.
