Mariah Carey will perform live from Times Square on ABC's Dick Clark's New Year's Rockin' Eve.
It will mark the first time in the 34-year history of the year-end special that a singer has performed from Times Square, the network said.
The 76-year-old Clark, long a New Year's Eve tradition, will be making his first television appearance since suffering a stroke last December.
Hilary Duff will host the West Coast portions of the show, introducing artists including The Bangles, Chris Brown, Sean Paul, The Pussycat Dolls, Sugarland, 3 Doors Down and 311. Duff will also perform.
