Mariah Carey delivered what could easily be classified as the worst performance of her 25+ year career on ‘Dick Clark’s New Year’s Rockin Eve with Ryan Seacrest’ tonight (December 31).

Helping more than one million people camped out in Times Square painfully ring in the new year (and don’t forget the millions watching at home), the annual ABC special got a dose of updated versions of the diva’s hits ‘We Belong Together,’ ‘Emotions,’ and more.

When not talking through the songs, Carey’s backing track gave out at multiple points during the performance.  Guess who gave zero f*cks?  That’s right…Miss Mimi.

Watch the horror inside:
