The show will also include a duet by Ed Sheeran and Sir Elton John – the first time they’ve performed together live - and other confirmed performers are The Black Keys, British folksters Mumford & Sons, Frank Ocean, Taylor Swift, Alicia Keys, current nominees Maroon 5, and Justin Timberlake.

This year’s presenters include Katy Perry, Jennifer Lopez, Prince , Carly Rae Jepson, actor Pauley Perrette and one of this year’s nominees Hunter Hayes.

The ceremony will be broadcast live from the Staples Center Los Angeles on 10 February.
