Two weeks ago, Claire Boucher, better known as Grimes, had to cancel three dates in Canada due to issues with her hearing. Today, she announced that her entire European tour has been shelved.

"It's depressing to cancel more shows, but we have to cancel all Grimes dates in Europe due to health issues," the Canadian electro-pop artist tweeted this morning (Oct. 31) to her more than 75,000 Twitter followers, adding a frowny-face emoticon. She followed that up immediately with, "I will be updating shortly about which shows will be rescheduled."

The last few months have been rough on Grimes. Back in August, she had all of her gear stolen after a performance in Manchester, England, and sprained both of her ankles within a few days of each other.

Grimes' European tour was scheduled to run between Nov. 13 in Bristol, England, and Dec. 1 in Utrecht, Netherlands. Her album 'Visions' was released to great acclaim earlier this year.
