The troubled singer received nominations in the categories of best new artist, record and song of the year for Rehab, pop vocal album, and album of the year for Back to Black.

Last night Winehouse said in statement: "I'm honoured to have my music recognised with these nominations - this is a true validation from people I respect and admire."
