Lily Allen has hit out at the Grammy Awards for not considering Lorde in the Best New Artist category.

The 'Hard Out Here' singer is less than impressed with the music awards for overlooking the 17-year-old singer from New Zealand in the category recognising new talent and has labelled the awards the ''SHAMMYS''.

She wrote on Twitter on Sunday (08.12.13): ''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 (sic)''

She later added: ''#SHAMMYS #lordemusic rocks (sic)''

While Lorde missed out on a Best New Artist nomination, she is still up for four awards including Record of the Year and Song of the Year for her smash hit single 'Royals'. The song has also earned her a Best Pop Solo Performance nod, while her album 'Pure Heroine' is up for Best Pop Vocal Album.

Best New Artist nominees at the 2014 Grammy Awards include Ed Sheeran and 'Thrift Shop' hitmakers Macklemore & Ryan Lewis.

The nominations were announced last week.
