The group will take part in a comedy skit the stars co-created with the brains behind the FunnyOrDie.com website.

The three-hour telecast, which will air on 21 May (14), will benefit 12 charity organisations fighting poverty in the U.S., Africa, Asia and Latin America.

John Legend, Sean 'Diddy' Combs, Adam Levine, Blake Shelton, Christina Aguilera, Will Ferrell, Jack Black and top Hollywood couple John Krasinski and Emily Blunt have already signed up to be part of the historical charity event.
