It appears that pre-show soundcheck worked.
Also returning is Jenny McCarthy, who will reprise her role as an on-site reporter providing commentary from the crowd throughout the night, which will include performances by Camila Cabello, Nick Jonas and Sugarland.
"I just want to take a sip of tea if they'll let me - they told me there would be tea", she said during the performance. "Oh, it's a disaster".
Later, in response to her hot tea "disaster", Carey tweeted "Found my tea!"More news: Manchester City reveal Gabriel Jesus has suffered MCL injury

Carey, 47, successfully opened last year's set with a rendition of the New Year's classic "Auld Lang Syne", but while she was performing her 1991 hit single "Emotions", she abruptly stopped singing, though her dancers continued performing behind her.
2018 is off to quite a start. After finishing "Vision of Love", Carey hinted that a part of her stage setting was missing. The temperature in Times Square when the ball dropped was about 9 degrees, but with wind chill factored in, it was negative 4, making it the second coldest New Year's Eve on record.
Whether or not Carey will be able to prove she has the chops she says she does or not remains to be seen, but we can bet it something spectacular, one way or another, will be seen and by millions and millions of people. She then went into a pretty convincing performance of Hero with a gospel choir backing her up.
Mariah told the audience: "I'm trying to be a good sport here". It's a shame she can't perform like she use to. You may watch Mariah Carey's "hot tea" moment in the video player below.
