Billie Eilish was one of the surprise guests at Coachella! The 2024 music and artists festival kicked off its annual two-weekend run in Indio, California, on Friday — and, as expected, this year’s lineup wowed the crowed with electric performances and unexpected appearances on stage. Headliner Lana Del Rey kicked off Coachella weekend with a dreamy hit-filled set that featured songs like “Summertime Sadness” and “Doin’ Time.” This marked Del Rey’s return to the Coachella stage for the first time in a decade — “exactly 10 years ago to the day,” she told the crowd.

Del Rey surprised festivalgoers in more ways than one, between making her way to the Main Stage on motorcycle through the crowd of thousands before welcoming major star power like Billie Eilish to join her in dueting “Video Games” and Ocean Eyes.”

On Saturday Eilish did a surprise DJ set on one of Coachella’s smaller stages called The Do LaB. She previewed a handful of new songs from her new album: “Lunch,” “L’Amour De Ma Vie,” and “Chihiro.” That last one is named after the main character in Hayao Miyazaki’s Spirited Away, and Eilish also teased it during a Zane Lowe interview on Friday. She also danced around with the camera to some of the iconic songs, and one of them was Eminem’s “Lose Yourself.” Check out couple of videos below:

Billie Eilish shaking her bu-t to an Eminem song is a thing I thought I would never see. Few years back, She said: “I was scared of Eminem. My whole life. Always. I, dude, terrified. That dude freaked the f**k out of me. Oh my God.” And of course, Eminem being Eminem came up with the best response – shouting out Eilish in a verse of one of his tunes. In ‘Alfred’s Theme‘, the lyrics read: “Homicidal visions when I’m spitting like this / But really I’m just fulfilling my wish of killing rhymes which is really childish / And silly, but I’m really like this, I’m giving nightmares to Billie Eilish.” It appears Em helped Eilish stop being so scared of him.
