In a series of tweets, he wrote: "I just plain DISAGREE. The kid (Bieber) deserved it. Grammy board u blew it on this one. The hardest thing to do is transition, keep the train moving.

"The kid delivered. Huge successful album, sold out tour, and won people over ... this time he deserved to be recognized and I don't really have any kind nice positive things to say about a decision I don't agree with.

"So to all those nominated ... you do deserve it. You worked hard and u earned it. (I) just feel like so did JB. (sic)"
