The Paper Planes hitmaker had been expected to join artists including Kendrick Lamar, The Black Keys, Tiesto, Missy Elliott and Hozier at the British Columbia event next week (16-19Jul15), but organisers have announced M.I.A. will no longer be on the bill.

The star reached out to devotees on on Thursday (09Jul15) to apologise to those who had been looking forward to watching her onstage, and revealed festival bosses were told of her unavailability some time ago.

She writes, "I'm very sorry about Pemberton. I thought it had been announced months ago when I actually canceled due to conflicting dates."

Meanwhile, organisers have declared the annual event will move forward as planned, despite a massive wildfire which has broken out near the site of the Pemberton Music Festival this week (begs06Jul15).

A representative states: "Public safety remains our number one priority. We continue to monitor the situation closely and communicate with authorities... At this time, with the current condition, direction and location of the fires, there are no plans to cancel the festival."
