Mariah Carey's performance during Dick Clark’s Rockin’ New Year’s Eve With Ryan Seacrest went haywire when the vocal track malfunctioned and threw off the singer's lip syncing onstage.
The audio malfunction occurred while Carey was preparing to sing her hit "Emotions." Her three-song set also included the hit "We Belong Together" and "Auld Lang Syne."
“I’m trying to be a good sport here,” a visibly frustrated Carey said as she stopped singing and tried to find her place, explaining to the crowd that the vocal track was missing.
The singer had suffered from a tight and difficult rehearsal schedule earlier in the night was unable to hear through her in-ear monitor, according to a source.
The source told Billboard, "She didn't have the kind of time that she usually gets for her 'Mariah-ness.'"
Carey was set to headline the show at 11:30 p.m. just before the ball dropped in Times Square at midnight.
The singer later tweeted about the incident, jokingly writing, "Shit happens. ... Here's to making more headlines in 2017."
A west coast broadcast of Dick Clark's New Year's Rockin' Eve with Ryan Seacrest aired unedited. A rep for Dick Clark Productions declined comment and directed Billboard to Carey's tweet.
