Lady Gaga Has Bronchitis: Pop Star "Devastated" After Having To Cancel Shows

Lady Gaga has reportedly fallen ill.

Amid her ArtRave: The Artpop Ball world tour, the pop star has been diagnosed with bronchitis, and forced to cancel multiple shows in Washington state. On May 28, Gaga took to Twitter where she apologized to her fans.

"I'm devastated I'm unable to perform this week. Ursula took my mermaid voice I've come down with horrible Bronchitis," Gaga wrote on Twitter, along with a photo of the Little Mermaid movie, in which Ariel makes a deal with Ursula to give away her voice in exchange for human legs.

Gaga was scheduled to take part in shows in Seattle, on Wed., May 28, and in Vancouver, British Columbia, on Fri., May 30.

"My deepest apologies to Seattle and Vancouver, we'll reschedule those shows & be back to make it up to you," Gaga added in a second tweet. "I [love] monsters. #sadgaga."

ArtRave: The Artpop Ball world tour is Gaga's fourth tour and was launched in support of her third studio album, Artpop, which was released on 2013. The tour has scheduled shows in North America, Europe, Oceania, and Asia. It began on May 4, 2014, in Fort Lauderdale, Fla. and will wrap on Nov. 24, 2014 in Paris, France.

Dependent on Gaga's health, ArtRave: The Artpop Ball world tour will resume on June 2 at the Viejas Arena in San Diego. From there, she will go on to San Jose, Calif. for her second show in June, on June 3, before getting a few weeks off ahead of her show in Milwaukee, Wis. on June 26.
