The 2012 Grammy nominees were announced last night during a star-studded concert, but it seems Justin Bieber has been left out of this year's nominations. His manager, Scooter Braun, is not happy that the hit pop star has been left out and tweeted a series of rants regarding his disagreement at the outcome of the nominations. 

Though Bieber released his hit "Believe" album back in June, none of his singles nor the album itself received any nods from the Recording Academy. 

Bieber had received two nominations last year: Best Pop Vocal Album for My World 2.0 and Best New Artist. However, he did not win any awards, as Best New Artist went to Esperanza Spalding. 

Despite being one of the most famous pop stars in the world today, it seems the Biebs has yet to receive a Grammy. 

However, not all of Scooter Braun's acts have been snubbed. Carly Jae Repsen, who is part of his Schoolboy Records management, received two nods last night. However, other acts such as The Wanted and PSY, did not receive any nominations as well. 

Braun tweeted his congratulations for Repsen's nominations last night but also expressed his displeasure on Bieber's snub.  "first...congrats to @carlyraejepsen . thought u deserved a best new artist nom, but proud Call Me Maybe got u 2 noms. so proud of u. second....this time there wont be any wise words, no excuses, I just plain DISAGREE. The kid 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 succesful album, sold out tour, and won people over... ...this time he deserved to be recognized and I dont really have any kind nice positive things to say about a decision i dont agree with."

However, Braun did congratulate all the other acts that have been nominated, saying: "So to all those nominated...you do deserve it.  You worked hard and u earned it. Just feel like so did JB. To his fans...looks like we get to stay the underdog a little longer. #BRINGIT. I got a lot more I can say but for now....Im gonna leave it at that. Congrats to all those who got nominated including our own CRJ. life is long, with many ups and downs, but we get to keep going, everyday brings a new opportunity. NOTHING GREAT EVER CAME EASY."

The Biebs has yet to comment on being snubbed by the Grammys.
