Grammy Award-winning singers Billie Eilish and SZA were among a group of surprise guests brought out during Justin Bieber’s weekend two headlining set at the 2026 Coachella Valley Music and Arts Festival into the early Sunday morning hours.

Bieber, returning to headline for week two of the desert-set music festival, immediately hugged Eilish who collapsed — laughing in what seemed to be equal parts embarrassment and delight — after she was pushed onto the stage to be serenaded by Bieber during a performance of his 2009 hit, “One Less Lonely Girl.” The headliner then brought her over to a stool on the minimally set-designed stage to sing the song. Bieber seemed to be delighting in the moment as well, laughing along with Eilish throughout the song.

The “Daisies” singer played the track as part of a section of his stripped-back Coachella headlining set where he pulls up old music videos on YouTube to sing along to. The portion of the set produced a rare sight — a current-day Bieber singing along with his shockingly young past self. The crowd went wild for nearly all songs during the throwback portion, but particularly when the crowd realized it was Eilish on the stage.

The “Wildflower” singer was not the only guest to join Bieber on the stage. He was also joined by SZA, who came out near the end of his set to perform with him. The pair surprised the crowd with their acoustic duet of her hit song, “Snooze.” Bieber’s Coachella crowd erupted when SZA took the stage.

Bieber told the “Kill Bill” singer he loved her “so much” before she admitted she was so nervous that she didn’t know how to get off the stage. The “Peaches” singer guided SZA off the stage, shouting their love for one another as she exited.

Big Sean, Sexyy Red and Dijon also joined Bieber onstage for performances throughout the set. The headliner had special guests during weekend one of the festival, but there were slightly more for the second weekend.

Weekend two seemed to be the favored choice for surprise special guests. PinkPantheress brought out a gaggle of famous faces during her Saturday Mojave tent set, including Janelle Monae, Zara Larsson, Tyriq Withers, Chase Infiniti, Manon of KATSEYE and more.

Addison Rae was joined by Olivia Rodrigo on the Coachella main stage earlier in the day. The pair performed Rae’s “Headphones On” and the first live performance of Rodrigo’s new single, “Drop Dead.”

Pop star Sabrina Carpenter wowed the audience at her Friday night headlining set by bringing out Madonna. The pair even sang a rendition of Madonna’s “Like A Prayer.” The hit song came back into the zeitgeist late last year after a video of Heated Rivalry star Connor Storrie dancing to the track went viral.

Karol G is set to close out the festival with a Sunday night headlining set.
