They all looked arrogant in the Iheart radio show too. BTW @Hopeful they probably got connected with the new executive director for the Grammy's at the show, they got introduced and possibly will be serving him for next year. They might even be tricked to winning and then last minute shamed if they do not do what they are told for the award show just like Ariana Grande (not saying she deserved anything because frankly she is not talented).
also..could it be that this show is predicting next year's award like guaranteed that they'll win because they already completed a deed?
That James Corden episode had some weird energy from the boys.
