Lily Allen has slammed the Grammy Awards for not nominating Lorde in the Best New Artist category.

The nominations for the annual awards show were announced on Friday night at a special concert in Los Angeles and Allen did not take news of Lorde's omission from the category well.

Allen took to Twitter to express her frustration writing, "Legendary producer Jimmy Jam, who is chairman emeritus of the Recording Academy, suggested that Lorde's omission was because she, in effect 'skipped a grade' by having such a successful debut song. 'She is still very new,' he told CNN. 'Sometimes I think the Grammy voters like to say, "Well, let's see what else you have before we say you're the best new artist".'AT WHICH POINT SHE WONT BE A NEW ARTIST!!! what crap.''

Lorde hasn't been snubbed by The Recording Academy however as she is nominated in four other categories; Song of the Year, Record of the Year, Best Pop Solo Performance and Best Pop Vocal Album.
