Mariah Carey has broken her silence on her awkward New Year's Eve show, saying she's "mortified".

A series of technical glitches revealed the singer lip-syncing during her performance in New York. She ended it early, walking off-stage.

In her first interview since, she told Entertainment Weekly she was let down by Dick Clark Productions.

"I'm of the opinion that Dick Clark would not have let an artist go through that and he would have been as mortified, as I was in real time."

While initially brushing off the viral incident with a tweet, she's now reportedly launching her own investigation into the glitches.

"It really was an incredible holiday season that turned into a horrible New Year's Eve," she told Entertainment Weekly.

"It's not going to stop me from doing a live event in the future. But it will make me less trusting of using anyone outside of my own team."

Not everyone's been left cringing - US host Stephen Colbert returned to The Late Show this year with his own Mariah moment.

"This was not her fault. Mariah, you're welcome to come on my show any time... I'm sorry, there's nothing in my prompter here," he said.

"Am I supposed to be singing right now?" he asked as dancers flocked around him, in a spoof not far from the original.
