Lorde may be about to add new awards to her already impressive list at the American Music Awards.

The 18-year-old singer - whose real name is Ella Yelich-O'Connor - has been asking fans on Twitter to vote for her.

She is nominated for Artist of the Year, Favourite Female Artist, Favourite Album and Favourite Artist in the Alternative Rock categories.

Lorde won six awards at the New Zealand Music Awards last week and has tweeted she'll attend the American Music Awards at the Nokia Theatre in Los Angeles later today.
