Mariah Carey took to the stage in Japan on Saturday night, to play the latest gig in her Elusive Chanteuse World Tour.
The video shows Mariah appearing to struggle through some of her most successful hits, including "Hero".
And it wasn't long before some of her biggest fans took to Twitter to express their thoughts about her performance.
The performance follows a tumultuous time for Carey, after she reportedly split from her husband of six years, Nick Cannon.
However, a representative for Carey has dismissed the negative comments, telling The Mirror: "The comments we have heard from fans have been great!"
