And now, for the grand finale, 2016 is taking out Mariah Carey live on stage pic.twitter.com/kfBJxXjepB — The Ostrich (@ALostrich) January 1, 2017

Mariah Carey really dropped the ball in Times Square on New Year’s Eve — with lip syncing that was decidedly out-of-sync.

Carey had been assigned to perform two of her hit songs, “Emotions” and “We Belong Together.”

But the singer appeared unable to hear her own song track, ultimately giving up and standing on the stage with closed mouth and a hand on her hip.

Meanwhile, her vocal track went on without her.

“Well, Happy New Year,” she huffed. “We can’t hear, but I’ll just go through the motions,” she said, later adding, “I’m trying to be a good sport here.”

“It was kinda like the ‘Saturday Night Live’ performance,’’ said Leslie Keeley of Manhattan, referring to Ashlee Simpson’s infamous out-of-sync turn on “SNL” in 2004. “The end of 2016 was not good for Mariah.’’

Carey had been heavily hyped by ABC as the star attraction of “Dick Clark’s Rockin’ Eve 2017.

And indeed, she made quite a splash — just not in the way the network had intended.

Twitter users went wild.
