Billie Eilish, 22, Admits She Had a 'Nightmare' Before Becoming Youngest-Ever 2-Time Oscar Winner for “Barbie”

"I'm so grateful for this song and this movie and the way that it made me feel, and this goes out to everyone who was affected by the movie and how incredible it is," Eilish said of 'What Was I Made For?'

Billie Eilish is a two-time Oscar winner at just 22 years old!

At the 2024 Oscars on Sunday, Eilish and her brother Finneas won Best Original Song for the tune “What Was I Made For?” from Barbie, beating out “I’m Just Ken" also from Barbie, as well as “The Fire Inside” from Flamin’ Hot, “It Never Went Away” from American Symphony, and "Wahzhazhe (A Song for My People)" from Killers of the Flower Moon.

The award marks Eilish's second Oscar; she won her first Oscar for Best Original Song for her James Bond tune "No Time to Die" in 2022.

"I had a nightmare about this last night," Eilish said after taking the stage and sharing a sweet hug with presenter Ariana Grande. "I didn't think this would happen, I wasn't expecting this. I feel so incredibly lucky and honored."

The singer went on to thank the Academy and Barbie director Greta Gerwig, saying, "I'm so grateful for this song and this movie and the way that it made me feel, and this goes out to everyone who was affected by the movie and how incredible it is."

Later, Eilish thanked her best friend Zoey for "playing Barbies with me growing up and being by my side forever." She then continued, "I want to thank like my dance teachers growing up. I want to thank my choir teachers — Ms. Bringham, thanks for believing in me. Ms. T, you didn’t like me but you were good at your job. And thank you to the Academy! I love you!"

Eilish and her brother, music producer and songwriter Finneas, wrote "What Was I Made For?" during a period of "frustration in writing," as she told Apple Music 1 host Zane Lowe in a July interview.

She said Gerwig asked the pair to write a song for the film after they were shown an early cut of Barbie with her and Warner Bros. executives. Though Eilish said she felt "purely inspired" by the movie, she quickly came to identify with the song's lyrics herself.

"I really don't mean this to come off in a conceited way at all, but I do this thing where I make stuff that I don't even know is ... like, I'm writing for myself and I don't even know it," she said at the time.

“Dude, the next week I was playing it in the car all day and playing it for everybody. And I was like, 'This is exactly how I feel. And I didn't even mean to be saying it,' " said Eilish.

During this year’s awards season, the song had success across the film and music industries, winning both best original song at the Golden Globes and song of the year at the Grammys.

Also up for the coveted award were "I’m Just Ken" from Barbie, “The Fire Inside” from Flamin’ Hot, “It Never Went Away” from American Symphony, and "Wahzhazhe (A Song for My People)" from Killers of the Flower Moon.

"I'm Just Ken" takes center stage in the hit movie as a full-on musical number performed by Ryan Gosling's Ken. Gosling also performed the tune during Sunday's ceremony in a show-stopping number.

Since the movie's release in July, the song has taken on a Kenergy of its own; it made an appearance on the Billboard Hot 100 in August and was parodied by Pete Davidson on Saturday Night Live in October.

In July, producer Mark Ronson told Vanity Fair that Gosling enjoyed the track so much when he first heard it that he requested to perform the song onscreen in the movie, leading Gerwig to rewrite an entire scene in order to fit in the performance.

“He really got [that] it had to walk this line of not being funny or parody,” Ronson told Vanity Fair. “But obviously, the song is also kind of ridiculous at times. So he was really amazing, and when he really did start hitting the big notes, I was like, ‘This dude is a vocal powerhouse!’”

Prolific songwriter Diane Warren wrote “The Fire Inside” for Eva Longoria’s directorial debut Flamin’ Hot. The biopic is based on A Boy, a Burrito and a Cookie: From Janitor to Executive by Richard Montañez, a man who claims to have invented Flamin’ Hot Cheetos.

Warren, who has written hits with superstars like Taylor Swift and Celine Dion, has a long history of nominations at the Oscars dating back to 1987. With “The Fire Inside,” she records her 15th Oscar nomination for Best Original Song. Though she hadn't won the category, she said “it’s the coolest thing” to be recognized.

“I won already. Whatever happens, happens. It's just a beautiful thing to get the respect of those I respect,” Warren told PEOPLE at the Billboard Power 100 ceremony in February.

Grammy winner Jon Batiste, 37, landed his second Oscar nomination for “It Never Went Away,” co-written with Dan Wilson, from his documentary American Symphony. The musician previously won Best Original Score in 2021 for his work on Pixar’s Soul.

American Symphony shows a year in Batiste’s life, exploring his rise to music stardom after the 64th Grammy Awards as well as his wife Suleika Jaouad’s leukemia diagnosis.

Director Matthew Heineman told PEOPLE the film initially began as a process film for Batiste’s composition of a symphony but became more when “life intervened.”

“American Symphony became a beautiful meditation on what it means to be an artist and to persevere during tough times and good times,” Heineman said.

Martin Scorsese’s Killers of the Flower Moon has garnered acclaim from all corners of the industry, landing the director an Oscar nomination and stars Lily Gladstone and Robert De Niro acting nods.

“Wahzhazhe (A Song for My People)" is composed by Scott George and sung entirely in the Osage language.

In an interview with Variety, George — the first Osage writer to be nominated for an Academy Award — admitted he was reluctant to create the song. “A lot of people get invited to our dances to just look on and see what we do. But they are ceremonials, and we don’t like for them to be filmed, or recorded,” he told the outlet.

“Wahzhazhe” plays at the end of the film as a drone shot captures a birds-eye view of an Osage gathering. Translating the lyrics to Variety, George said, “‘I’m asking my people to stand up.’ The next phrase translates as ‘God made it for us.’ The expression I’m trying to say is, ‘Stand up, be tall and be proud. We’re still here after all of that.'"
