Last year Mariah was left humiliated when she was hit with multiple technical difficulties and accused of miming her set but she is looking forward to redeeming herself this year and co-hosts Ryan and Jenny want her to do well.
Ryan told E! News: ''We are really not in control. This is so different than doing a show on stage or in an arena. You are in Times Square with all the elements including windchill of -5. It's not like that on the set.
''This year we are anxious to see Mariah come back.''
Jenny is thrilled that Mariah, 47, is returning, saying: ''How many times would we all like a second chance at something? I think it's a wonderful thing.''
Mariah previously claimed she felt ''vilified'' after her 2016 performance.
She said: ''I didn't obsess over the New Year's Eve thing. I mean, I was upset about the fact that people didn't understand, but it's like, I can only explain it like this to you. It's like I'm the only one that has to make five million comebacks... For me there are different rules, I don't know why. I don't know why it's not OK that I was just vilified by the situation. It's very difficult, especially the way the business is now. I truly love music and always have. It's not like ... 'Oh, here's a way to get famous.' It wasn't any of those things. It was my release, it was my everything and it still is. So I think that I'm just grateful that people still tune in.''
However, she announced her decision to return on December 31 in a joint statement with Dick Clark Productions.
They said: ''We can all agree that last year didn't go exactly as planned and we are thrilled to move forward together to provide America with an incredible night of music and celebration on Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2018. See you in Times Square!''
From 'Happy' to 'Banana Pancakes', these are soaked in positivity.
