Yep, it's true and you aren't the only one shocked.
Justin's manager, Scooter Braun, went to Twitter to showcase his frustration at the academy's snub.
"This time there won't be any wise words, no excuses, I just plain DISAGREE," Scooter tweeted to around 2 million people!
"The kid deserved it. Grammy board u blew it on this one."
He continued, "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."
We TOTALLY agree with Scooter! Believe was one of the best albums of the year and totally deserves to be nominated for a Grammy! Not to mention, Justin's one of the hardest working people in the bizz!
Scooter did find time to congratulate Carly Rae Jepsen and the others (Ed Sheeran, what what!) for their nominations.
Check out an entire list of the 2013 Grammy Awards nominees below! Was there anyone else left out that deserved to be nominated? Did Justin get ripped off? Let us know!
