Mac Miller has been having a great 2015, but now, things seem to be winding down for the GO:OD AM vocalist.

The Pittsburgh native has postponed the Australian leg of his tour due to exhaustion.

Miller took to his Twitter account to announce that he was cancelling his plans to visit Australia and New Zealand as he wrote:

“After over 90 days on the road…I have to cancel New Zealand and Australia. I am so sorry to all my fans out there. My voice is gone, my body is exhausted, and I can not guarantee you guys an 100 percent performance. I don’t want to give you anything less than my best.”

However, the rapper later reassured his fans that there would be rescheduled dates.

We’re  sending our get well wishes to Mac Miller.
