Where to watch
The awards kick off on Sunday, Nov. 24, at 8 p.m. ET on ABC.Ciara will host the show this year.
Viewers will see a wide mix of performances, including Billie Eilish, Selena Gomez, Jonas Brothers, Camilla Cabello, Dua Lipa, Lizzo, Thomas Rhett, Shania Twain, and a much anticipated number from Taylor Swift.
Speaking of Swift
The singer is set to perform a medley of her hits, but will she include songs from the masters that Big Machine Records and Scooter Braun now own? She's allowed to, but it's not clear if she will after a public dispute with her former label. In a statement released Monday, Big Machine Records said it had "agreed to grant all licenses of their artists' performances to stream post show and for re-broadcast on mutually approved platforms."
