Lorde described Coachella Valley Music and Arts Festival as "mental" when she took to the stage at the weekend.
The 17-year-old star performed at the event in Indio, California on Saturday (12.04.14) and was met with huge cheers.
She told the crowd: "This is actually the first big thing I ever booked. I said, 'Holy f**k, we booked Coachella'. I was screaming on the phone. We are so lucky to be here. This is mental."
According to Entertainment Weekly, the 'Royals' hitmaker thanked the audience for making the dreams of a "kid from New Zealand" come true.
She also took to Twitter today (14.04.14) to thank fans and wrote: "coachella week 1 all done, and we go out with blister feet and dusty hair and most importantly happy ears! goodnight freaks; we love you so (sic)."
After Lorde's performance, Pharrell Williams appeared with several guest stars, including Snoop Lion, Nelly, Busta Rhymes, Puff Daddy and Gwen Stefani.
Solange Knowles performed Kate Bush's hit 'Cloudbusting', before being joined by her sister Beyonce.
Coachella continues next weekend and artists on the bill include Arcade Fire, Beck and Calvin Harris.

Eminem and Rihanna performed 'The Monster' on live television for the first time at the MTV Movie Awards last night (13.04.14).
The pair headlined the two-hour show at the Nokia Theatre in Los Angeles, which also included performances from Ellie Goulding and Miriam Bryant, in a preview of their upcoming mini-tour which is set to travel to Los Angeles, New Jersey and Detroit this summer.
Rihanna entered the stage first, followed shortly after by Eminem and they, along with a backing band, managed to overcome technical faults to perform a crowd-pleasing rendition of their hit single for the first time on live television.
The musical pair first collaborated on 2010 single 'Love the Way You Lie' before reuniting for 'The Monster' - which Eminem, 41, released as the fourth single from his album 'The Marshall Mathers LP 2' in October last year.
Speaking previously about working with Rihanna, 26, he said that 'The Monster' was "not necessarily a sequel, as much as it is a revisitation" to his past.
He added: "To me, it's more about the vice, and it's more about the nostalgia."
Ellie Goulding took to the stage for a rendition of her single 'Beating Heart', which features on the recently released sci-fi/action film 'Divergent', while electronic DJ-producer Zedd joined her before Matthew Koma and Miriam Bryant took to the stage to play their track 'Find You.'

James Corden claims presenting the BRIT Awards was "horrid".
The comic admits having an audience that "don't listen to anything you say" was the most frustrating aspect throughout the five years he hosted the annual music ceremony, and it's something he won't miss now that he has stepped down.
Speaking during the 'Michael McIntyre Chat Show', James said: "It was horrid. It was so much fun the week leading up to it and you get to see the bands, and then it is live and you are in a room full of people that don't listen to anything you say. People who beg for a ticket and then pretend they are too cool to be there. They are chatting drinking and eating."
James, 35, admits he will miss the show following his last stint as a host in February but thinks the BRITS would benefit from having a younger host.
He added: "I enjoyed doing it and I'm sure when it comes around in February I will miss being a part of it. But it's time to hand it to someone younger and cooler."
Meanwhile, speculation as to who will take over has been rife with Radio 1 DJ, Nick Grimshaw, 29, expressing interest in the job while James has championed Emma Willis, 38.

Peaches Geldof was planning a secret Australian TV project just weeks before her death.
The 25-year-old star, who was found dead at her home in Kent, South East England, last Monday (07.04.14), was hoping to spend three months Down Under to film a new TV show, it has been revealed.
Speaking to Aga Living Magazine prior to her death, she said: "I can't say what it is yet, but I'll be there for three months. The babies will come with me because obviously I wouldn't leave them for that long."
The mum-of-two also elaborated upon her attachment parenting beliefs in one of her last interviews, explaining why she never left her children Astala, 23 months, and 11-month-old Phaedra - who she had with her husband Thomas Cohen - to cry alone.
She explained: "When babies are crying, they are too young to understand you haven't left them forever, so they are terrified."
The star's youngest son was tragically found at her side after her death and insiders hope her family will take "comfort" from the fact she didn't die alone.
A source said: "The hope is that Phaedra is so young he wasn't aware of what was going on. The most important thing is that he's OK.
"It is devastating for Tom that he wasn't there but it couldn't have been avoided."
Peaches' body has now been released by coroners so plans for her funeral can be made. Her cause of death remains unexplained.

Josh paid tribute to his late co-star Philip Seymour Hoffman in his acceptance speech.
He said: "It was so cool to have Philip in our movies. He's one of the actors I've looked up to my entire life. I know if Philip were here he would think this was really cool."

Lee Ryan has reportedly been pleading with Jasmine Waltz to take him back.
The 'Blue' singer split with his fellow 'Celebrity Big Brother' star girlfriend last month, but following his arrest on suspicion of drink driving in the early hours of Saturday (12.04.14) morning, it's been revealed he's been trying to get her back for the past week.
A source told the Daily Star newspaper: "Jasmine is sick of Lee's antics. All last week he was trying to persuade her to come back to London to patch things up."
The 30-year-old star - who stunned viewers when he ditched love interest Casey Batchelor for the American model on the Channel 5 reality show - is said to have cheated on Jasmine, 31, with a man, according to claims she made on her Twitter account.
But she's since been showing him what he's missing by refusing to take his calls and partying at the Coachella Valley Music and Arts Festival in her native California, where she's said to be getting close to Blur rocker Dominic Howard.
The source added: "Jasmine ducked talking to him.
"Then Lee found out she was going to Coachella, which upset him deeply.
"He knew Dominic's band were there too."
Lee has since been charged with failing to provide a breath specimen and criminal damage, and the father-of-two has confessed he will be seeking help for his "problem" at rehab.
He said: "Me going to rehab isn't a cop out ... I am doing this because I have finally admitted I need help. I want to stop hurting the people around me."

Kelly Osbourne has told Paris Hilton to "grow up".
The 'Fashion Police' host lashed out at the socialite following an incident at the Coachella Festival in California this weekend, which saw the 29-year-old presenter and her friends approached by Paris at an informal VIP area, only for things to quickly turn sour.
Paris reportedly glared at Kelly and stormed off after branding her a "b***h", prompting her former pal to last out on twitter.
In a post which has since been deleted, Kelly wrote: "Please grow up, there is no need to act like a child you could of joined us it's not 2005 no one cares. (sic)"
The pair are said to have continued the row in private, and Kelly believes Paris, 33, was just "attention seeking".
A source told the Daily Mirror newspaper: "As far as Kelly is concerned, this is something out of nothing. Paris is being ridiculously sensitive and attention-seeking.
"Kelly was sitting with some friends, minding her own business, when Paris suddenly started bitching and moaning, and slagging her off.
"She was asked by someone else to join the group, but declined and swanned off. The pair didn't speak for the rest of the weekend."
The pair have previously clashed in the past, with Kelly branding Paris a "bad influence" on young girls eight years ago.
However, they later made up, though Kelly admitted she didn't trust her friend with her secrets.
She said: "We have fun together. I know that whatever I tell her, she tells everyone anyway, but I've always known she's not the friend that you tell your deepest secrets to.
"She's a fun person, and there is a sincerity about her."

Johnny Depp is hopeless with modern technology.
The 50-year-old actor - who has children Lily-Rose, 14, and Jack, 11, with former partner Vanessa Paradis - says his kids have learned not to ask him for help with their homework because he can only advise on music or history.
He said: "As far as technology... let me put it to you this way.
"My kids are smart enough to not come to me for any questions about the computer, even homework for that matter.
"Unless it's got to do with history or the future or music, I'm good.
"If it's math and all that, I'm down the road."
The 'Transcendence' star also admitted one of the "best experiences" of his life was cramming into an electric Tesla car with its founder Elon Musk, director Wall Pfister and co-stars Paul Bettany and Rebecca Hall - but their fun was cut short after they were stopped for speeding.
Johnny is quoted by The Sun newspaper as saying: "I had one of the best experiences I've ever had. The director introduced me to Elon Musk at Tesla. He came and visited the set and we had a ride around in his car but then the police pulled us over.
"We had a first - maybe the first -Tesla jam. I was in the front seat while Paul Bettany was sitting on my lap. Rebecca and Wally were in the back. Elon was driving and we were pulled over speeding."
While the 50-year-actor and his peers found the incident hilarious, he claims the policeman wasn't amused.
He added: "Elon had a good sense of humour about it. The cop did not. He needed a humour chip. But it was a good time, nonetheless."
Tesla are renowned for their fully electric luxury sportscars with the Tesla Roadster able to accelerate from zero to 60 mph in under 4 seconds with top speeds of up to 125mph.

Penélope Cruz could be set to star in the next James Bond film.
The 39-year-old actress is reportedly in the running to play the spy's lover in the upcoming next instalment, which will be a follow up to 'Skyfall' which starred Cruz's husband Javier Bardem as the villainous Silva.
Director Sam Mendes is reportedly keen to get the brunette beauty to star alongside current Bond actor Daniel Craig, who will play the super-spy for the fourth time next year.
A source told The Sun newspaper: "Bond bosses have been chasing her [Cruz] since Daniel became 007 in 2006. But schedules and her pregnancies meant it never materialised."
Cruz - who has 3-year-old son Leonardo and 9-month-old daughter Luna with Bardem - would follow in the footsteps of actresses including Halle Berry and Gemma Arterton to become a 'bond girl' and would also star alongside 'Skyfall' actors Ralph Fiennes and Naomi Harris.
However, the production team behind the film have so far made no comment as to whether they have approached Cruz for the role.
The source added: "At this stage no one at Sony will confirm it."
'12 Years a Slave' star Chiwetel Ejiofor has been tipped to play the main "baddie" in the film with Swedish beauties Ida Engvoll and Disa Ostrand already having completed screen tests to play extra love interests.
Filming is expected to begin in November with a release date of October 2015.

Simon Cowell will want a baby daughter next, according to Amanda Holden.
The 54-year-old music mogul welcomed his first child, son Eric, with Lauren Silverman in February and his 'Britain's Got Talent' co-star predicts he will want another child.
Amanda recalled Simon's sweet demeanour around her own daughters, Lexi, eight, and Hollie, two, whom she shares with husband Chris Hughes.
She said: "Simon was so cute when Hollie sat on his lap and shared a biscuit with him. Now when she sees Simon on TV, she calls him 'My Simon'. I think Simon will have more children - he'll want a girl next."
Amanda, 43, also admits she never thought she'd see the day Simon became a father.
She added to Closer magazine: "If a fairy had come along and said, 'Simon will be cradling a son this year', I would have laughed in its face. He has softened so much since he became a dad.
"I think Simon thought children and families weren't for him, but he is so happy. Simon brings Eric on set at 'BGT' and he's adorable. He has Simon's lips. He's such a good baby!"
