Justin Bieber’s second Coachella headlining set was packed with star power, most notably marked by an appearance from his long-time friend and self-described superfan, Billie Eilish.

On Saturday night (April 18), the 32-year-old pop icon returned to the Indio, California, stage for a high-energy performance. A highlight of the evening occurred when he invited Eilish to join him for a nostalgic rendition of his 2009 breakout hit, “One Less Lonely Girl.”

The duo shared a lighthearted moment on stage, laughing and embracing while Bieber serenaded the singer during a segment of the show dedicated to his early YouTube-era roots.

Eilish has frequently credited Bieber for his mentorship and emotional support throughout her rise to global fame. “He has been incredibly helpful in navigating the pressures of this industry,” she shared during a 2020 interview with SiriusXM. “He’s a genuine friend who makes me feel understood when things get overwhelming.”

Bieber didn’t stop there—his set was a revolving door of high-profile collaborators. He welcomed SZA for a soulful, acoustic version of her 2022 anthem “Snooze,” tapped Sexyy Red for an electric performance of “Sweet Spot,” and teamed up with Big Sean to revisit fan-favorites “As Long As You Love Me” and “No Pressure.”

This massive Coachella showing comes on the heels of a historic streaming week for Bieber. Following his opening weekend performance—which showcased tracks from his 2025 project Swag alongside classic hits—he recorded his highest daily streaming total since July 2025, pulling in 24.6 million streams on April 12, according to Luminate.
