During her annual rendition of “All I Want for Christmas Is You,” Carey missed most of the high notes she’s famous for, leaving her backup singers to pick up the slack. It was disappointing.

According to TMZ, Carey was actually supposed to pre-tape her segment Tuesday but allegedly blew off her scheduled time slot for a phone meeting with her divorce attorney. When she finally showed up, three hours late, NBC execs sent her home without filming.

She apologized and the network gave Mariah a last-minute spot on Wednesday’s broadcast, however she had to do it live. Listen to the isolated vocals from her live performance above, and download the prerecorded version below.
