Mariah Carey has a reputation as one of the biggest divas in showbiz.
And true to form, she had an epic meltdown in front of millions after botching her headline performance at America's biggest New Year's party.
Carey lost the plot after her attempts to lip-sync completely fell apart, crying: "I'm trying to be a good sport here."
It's believed the wrong song was played and Carey couldn't hear what she should have been singing on stage.
With a face of thunder, she stropped around the stage saying: "'We didn't have a check for this song... we're missing some of the vocals, but it is what it is.
"I'm just going to let the audience sing."
"We didn't have a sound check for this New Year's baby, it is what it is."
"Get these monitors on please."
During a second song, she frequently gave the mic to audience members in the front row ,before saying to one of her backing dancers: "Just for laughs, do the lift."
Carey added: "I wanted a holiday too, can't I just have one."
As many as 2 million people, surrounded by a ring of 40-ton sand trucks and some 7,000 police, gathered in the "Crossroads of the World" to watch the glittering sphere complete its minute-long drop, marking the beginning of 2017.
