(December 7, 2012)--Justin Bieber didn't get a single Grammy nomination this yaer and his manager, Scooter Braun, said on Twitter the Grammys "blew it on this one."

Braun argued that Bieber released a successful album with "Believe" and had a sold-out tour this year.

Bieber also was the big winner just a few weeks ago at the American Music Awards.

He was considered a shoo-in to win the Best New Artist Grammy in 2011, but was upset by Esperanza Spalding.

Braun said to the fans, "Looks like we get to stay the underdog a little longer."

Spalding got three nominations this year.
