The 17-year-old songstress also earned the best pop solo performance for her debut album 'Pure Heroine' last night at LA's Staples Center.
"This is the one thing I didn't expect tonight. I also thank fellow nominees and category losers, Bruno Mars, Justin Timberlake and Katy Perry for being inspirational vocal artists," Lorde said while receiving the best pop solo performance award.
She missed out on a hat trick by losing her third nomination, record of the year to Daft Punk's 'Get Lucky' featuring Pharrell and Nile Rodgers.
Best country album award went to Kacey Musgraves for her 'Same Trailer Different Park'.
The awards show was hosted by LL Cool J.
