New Year's Eve will be a momentous night for many country music fans - even those who aren't heading to Nashville's big celebration with Keith Urban.
Of course, Times Square will be in the center of the celebration and the show.
"We can all agree that past 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", Carey said in a joint statement Friday with Dick Clark Productions, which runs the show.
Carey joins previously announced Times Square performers including chart-topping singer/songwriter Camila Cabello, multiplatinum singer/songwriter and actor Nick Jonas and award-winning duo Sugarland.More news: Mark Hamill pays tribute to Carrie Fisher: 'No one's ever really gone'
