Lady Gaga has been forced to cancel several concerts due to a battle with bronchitis.

"I'm devastated I'm unable to perform this week. Ursula took my mermaid voice, I've come down with horrible bronchitis," she tweeted. "My deepest apologies to Seattle and Vancouver, we'll reschedule those shows & be back to make it up to you. I [heart] monsters. #sadgaga"

Gaga kicked off her ArtRave: The Artpop Ball tour on May 4 in Fort Lauderdale, and the 5-leg concert series has her doing a total of 75 shows in Asia, Europe, North America and Australia.

Hopefully she heals soon!
