The hits just keep on coming for Mimi!

Mariah Carey kicked off her tour in Japan on Saturday, and let's hope she was simply under the weather, because the songstress' voice completely gave out and she couldn't hit any of the high notes she's famous for. The legendary diva was slammed by fans for her performance, and after watching the video, we're almost in disbelief!

Adding to the problems, the singer's microphone completely broke during her performance of "We Belong Together" and she appeared to forget the lyrics to her songs periodically throughout the night.

What has Nick Cannon done to her?!
