She made amends by offering to sing live Wednesday.

You've kept me here, in your hearts, and I keep you in mine always. We are #lambily! #ThereForMe ?? ??

She even shared a snap from backstage of her getting ready.

Later on stage, dressed in red, Carey appeared visibly frustrated with her ear piece and seemed to struggle with her breathing, as her voice cracked at times.

Gawker called her performance \"disappointing,\" while Deadspin, which posted an unedited raw version of her vocal track, called it a \"disaster.\"

Mimi's longtime fans, however, jumped to her defense on social media, lauding her bravery for singing live.

What do you think?
