Simon Cowell -- Grammys Screwed Justin Bieber ... He Deserved a Nomination

Justin Bieber deserved at least ONE Grammy nomination this year for his hard work ... but no ... he got shafted by the uppity snobs at the Recording Academy -- so says Simon Cowell.

Simon was out in L.A. Thursday night -- for the launch of his new X Headphones -- when we asked about Bieber's Grammy snub. He told us, "You know what? He deserved one [nomination], I think. But they can get a bit snobby sometimes."

But Simon's not worried about the Biebs, adding, "He won't be crying too much. He's doing fine."
