Miley Cyrus Cancels 30 Mins Before Show -- Too Sick to Sing

Just days after the death of her dog, Miley Cyrus is suddenly too sick to sing -- she just cancelled her concert tonight in Charlotte, NC at the last minute.

Miley's rep tells us, the singer cancelled 30 minutes before the start of her Bangerz concert at Time Warner Cable Arena because she has the flu.

Fans who showed up with tickets were turned away, but we're told refunds will be issued.

We're told her concert tomorrow night in Raleigh will go ahead as scheduled.
