Miley Cyrus, Mariah Carey, and Every Other Holiday Special Coming Your Way

Following her inaugural special last year, Miley Cyrus will return for her second annual New Year's Eve celebration on NBC. Cyrus co-hosted last year's show, produced by "Saturday Night Live" head honcho Lorne Michaels, with Pete Davidson but has traded the comedian for a new cohost: Dolly Parton. The singer announced the big news on Nov. 21 in an Instagram video featuring Parton. The special will take place in Miami, which Parton teases will be a "legendary" event for viewers.

How to watch: Dec. 31 from 10:30 p.m.-12:30 a.m. ET on NBC, or stream live and on-demand on Peacock.
