Singer Grimes has axed her upcoming European tour due to ongoing health issues.

The Canadian star, real name Claire Boucher, scrapped a series of shows in her native country earlier this month (Oct12) because of hearing problems and now she has cancelled her gigs overseas as she continues to struggle with tinnitus.

Grimes was due to kick off her trek in Bristol, England on 13 November before wrapping up in Utrecht, Netherlands on 1 December (12).

In a post on Twitter.com, she writes, "It's depressing to cancel more shows, but we have to cancel all Grimes dates in Europe due to health issues... I will be updating shortly about which shows will be rescheduled."
