It's two out of four for Lorde. The Auckland singer has won her second Grammy for Song of the Year, after earlier winning the award for best pop solo performance.
She missed out on Record of the Year, which was won by Daft Punk, and Best Pop Vocal Album award, which went to Bruno Mars for his album Unorthodox Jukebox.
Speaking backstage about her Grammy wins, Lorde said "the weirdo won out" and that she was "stoked" about the wins.
Asked about her music and style being "unconventional'', she said: "Yeah, this time the weirdo won out."
She said her highlight of the night was seeing the Daft Punk 'robots' in person, saying she was a "big fan".
The 17-year-old, who is too young to drink alcohol in the US, said she was planning to spend the night "hanging out" with her family and "drinking a lot of sparkling water".
She also revealed she has big plans for the year ahead, but refused to give away what they were, saying simply: "You will find out."
Earlier in the evening, she and producer/co-writer Joel Little - joint winners of the Song of the Year prize - took to the stage to say their thanks to their families, managers and record labels.
"Thanks to everyone who let this song explode," she said.
Accepting their award, Little took the microphone first, saying: "Oh wow, this is intense. Ella's making me go first.

"I just want to say, we made this song originally just to give away for free and to be here now in this room with so many legends and people who we all admire is a complete honour, so thank you for that.''
Little thanked his wife, children and family, as well as his manager and Lorde, adding: "You know I think you're amazing.''
Lorde praised her co-writer and producer Joel Little for her success, saying she wouldn't be on stage accepting awards if it wasn't for him.
"This guy's nurtured me through kind of my first years of song-writing, which I will forever owe him,'' she said.

Earlier, for her first award win, Lorde took to the stage sounding nervous, opening with a shy "hello".
"This is the one thing I didn't expect the most tonight," she said before paying tribute to her fellow nominees. She didn't thank anyone else -- perhaps indicating she was hoping to thank more later.
"I think mostly to Bruno, to Sara [Bareilles], to Katy, to Justin, I have been so inspired by all of your vocal performances at some point in my life, so thank you."
Lorde and Little join a prestigious list of New Zealanders who have won Grammys.
The first was Kiri Te Kanawa in 1983 for the best opera recording of The Marriage of Figaro.
The most recent was Kimbra, who last year won two - best pop duo/group performance and record of the year with Gotye for Somebody that I Used to Know.

Prime Minister John Key said her win had sent Kiwis into a national standing ovation.
"And New Zealand rises to its feet. @lordemusic has won her first Grammy for best pop solo performance. Awesome,'' he tweeted.
Auckland Mayor Len Brown also tweeted his congratulations, saying: "Lorde just made 1.5 million Aucklanders so proud.
"Music history for a 17 year old from the Shore at the Grammys.''
More praise has been pouring in for Lorde, with the New Zealand Olympic team adding their support.
"Way to go @lordemusic! you are #makingusproud BIG TIME!,'' @nzolympics tweeted.
Actor and comedian Rhys Darby posted: "Congrats @lordemusic keeping it so real it's unreal. You're amazing! #Grammys''

Earlier, she performed as the second act at the awards ceremony in Los Angeles.
In a move that may come as a surprise to her fans, Lorde did not show up on the red carpet at the 56th Grammy Awards, where celebrities are typically asked which designer they are wearing.
But she was soon seen on stage, as the second performer of the night, singing her smash hitRoyals.
Host LL Cool J introduced her as a "global sensation'' who had taken the music world by storm.
The chart-topper performed a slight rearrangement of the hit song. Her trademark long curly hair was straightened and she wore an unusually conservative outfit of a white buttoned-down sleeveless shirt and black trousers.
The moody performance, with a darkly-lit stage and stone angels in the background, was met with rapturous applause from the star-studded crowd.
It was in stark contrast to the show's opening act, a grinding duet by husband and wife superstars Jay-Z and Beyonce.
Contrary to reports that she would be wearing a New Zealand designer to the awards, the white shirt Lorde wore for her performance was reportedly Prada and the pants by Celine pants.
The clingy black dress she changed into afterwards was reportedly from Balenciaga's fall collection.
New Zealand hip hop DJ and producer P-Money tweeted: "Wow. Big up @lordemusic and her whole crew. That must have been a thrill to perform #grammys"

Earlier today, the North Shore teen tweeted a photograph of herself in her dressing room getting ready for the Grammys, as well-wishes pour in from her fans and celebrities alike.

An estimated 30 million viewers from around the world tuned in to see the 17-year-old perform at the Staples Centre in Los Angeles for the event, which screened live on TV2 today.
The Devonport-born star flew out of Auckland on Tuesday with boyfriend James Lowe, mother Sonja and sister Indy and has since hobnobbed with the music world's elite at pre-Grammy parties.
Meanwhile, her co-writer and producer Joel Little tweeted a picture of himself in his tuxedo and bow-tie with a party cup, saying: "Ok Grammies time, got my cup just like Jay Z, cheers to everyone for the well wishes."

Lorde - the youngest Grammy nominee this year - was the bookies' favourite to take out the gong for best song with Royals, which was No 1 on the Billboard Hot 100 chart for nine consecutive weeks last year - the first time a New Zealand solo artist has reached the US spot.
She was up against Macklemore & Ryan Lewis, Pink, Bruno Mars and Katy Perry
