Billie Eilish took the Grammys stage with her brother Finneas to deliver a moving performance of her Grammy-nominated song "What Was I Made For?" from "Barbie."

The singer wore an outfit inspired by 1965 Poodle Parade Barbie, which she shared on her Instagram ahead of the Grammys.

Heading into the night, the seven-time Grammy winner was nominated for six Grammy Awards, including record of the year, song of the year, best pop solo performance, best pop duo/group performance, best song written for visual media and best music video.

She and her brother have already won best song written for visual media for "What Was I Made For."

SZA performed her hit songs “Snooze” and “Kill Bill" Sunday night.

Heading into the evening, the singer was nominated for nine Grammys, the most of any artist this year.

She has already won for pop duo/performance for “Ghost in the Machine” ft. Phoebe Bridgers.

Karol G became the first woman to win the Grammy for best música urbana album, taking home the trophy Sunday night for her album "Mañana Será Bonito."

The Colombian singer said she was "super happy" to have won and called it a "beautiful thing."

The Grammy for best música urbana album was first handed out in 2022. Bad Bunny is the only other artist to win in the category, having taken home the trophy twice.

Trevor Noah took the Grammys stage to welcome everybody to the 66th annual awards show following Dua Lipa's opening performance.

Just as the comedian was noting how women dominated this year in music, Taylor Swift made her way through the audience.

"Are you seeing what's happening right now? As Taylor Swift moves through the room, the local economy around those tables improves," Noah joked. "Can you see that? Look at this magic right now. Look at this magic. Lionel Richie? Now Lionel Wealthy."

Noah also commented on Universal Music Group pulling its music off TikTok amid a licensing dispute.

"So, right now the CEO of TikTok is sitting at home, watching this show, eating ice cream [and] crying, seeing all his exes in one room," he said.

Celine Dion took the stage to present the Grammy for album of the year to Taylor Swift for "Midnights."

"When I say that I'm happy to be here, I really mean it from my heart," Dion said before presenting the award. "Those who have been blessed enough to be here at the Grammy Awards must never take for granted the tremendous love and joy that music brings to our lives and to people all around the world."

Taking the stage to accept the award, Swift said, "I would love to tell you that this is the best moment of my life, but I feel this happy when I finish a song, or when I crack the code to a bridge that I love, or when I'm shot-listing a music video, or when I'm rehearsing with my dancers or my band, or getting ready to go to Tokyo to play a show."

"For me, the award is the work," she continued. "All I want to do is keep being able to do this. I love it so much. It makes me so happy."

With this win, Swift becomes the first artist to win in the category four times. Frank Sinatra, Stevie Wonder and Paul Simon have each won album of the year three times.

Other nominees in the category included Jon Batiste for "World Music Radio," boygenius for "The Record," Miley Cyrus for "Endless Summer Vacation," Lana Del Rey for "Did you know that there's a tunnel under Ocean Blvd," Janelle Monáe for "The Age of Pleasure," Olivia Rodrigo for "GUTS" and SZA for "SOS."
