Key collaborations and performances
Billie Eilish and Justin Bieber have appeared together in a few notable live moments and studio contexts. The most prominent shared performance came during Bieber’s Los Angeles stop of his Justice tour in late 2021, where Eilish joined Bieber to perform "Therefore I Am" and a cover of "I Love You" by Woodkid. They also appeared together at iHeartRadio’s Billboard Women in Music 2019 brunch, performing "Bad Guy" and later sharing the stage for Fallon’s Tonight Show segment. These events are summarized in the table below.
| Event | Date | Shared performance | Notes |
|---|---|---|---|
| Justin Bieber Justice Tour, LA | 2021 | “Therefore I Am,” “I Love You” (Woodkid cover) | Joint onstage moment during Bieber’s tour |
| iHeartRadio Women in Music / Tonight Show | 2019 | “Bad Guy” | Live TV cross-promotion at iHeartRadio event |
No formal studio collaboration released
As of now, Eilish and Bieber have not released a standalone studio single together. While they have appeared on the same bill and shared the stage, they have not dropped a duet or co-written track for commercial release. Rumors occasionally circulate on social platforms, but there has been no official announcement of a recording collaboration.
Musical parallels and audience overlap
Both Billie Eilish and Justin Bieber emerged as defining pop voices of the late 2010s, albeit with distinct aesthetics. Eilish’s signature intimate, bass-forward sound contrasts with Bieber’s polished R&B-pop evolution, yet they share a generational foothold among Gen Z listeners and benefit from overlapping streaming demographics. These similarities underpin fan speculation about pairings, but musically their paths remain largely separate.
Social media interactions and mutual acknowledgments
Eilish and Bieber follow each other on public social accounts and have acknowledged one another in interviews and live settings. While not deeply personal confidants, they operate in the same celebrity ecosystem and have shown brief, cordial moments in public. Industry professionals sometimes group them in conversations about youth-driven genre shifts, but their working relationship centers on coinciding timelines rather than ongoing co-creation.
Fan expectations versus reality
Among casual and ardent fans, the idea of a Billie Eilish and Justin Bieber song together remains popular. Media speculation often conflates shared events with unreleased material. Clear, factual distinctions between onstage appearances, potential demos, and officially released music help manage expectations. The pair’s distinct fanbases occasionally merge at streaming events or awards shows, but no binding musical project has materialized.

Context and career trajectories
Billie Eilish arrived with a whisper-pop, producer-forward approach that redefined mood-driven pop in the late 2010s. Justin Bieber evolved from teen pop phenomenon to an R&B-inflected adult contemporary presence. Their timelines intersect at cultural moments, but their artistic priorities and sounds diverge. Industry observers sometimes group them when discussing streaming-era youth culture, yet their catalogs remain independent bodies of work with no merged release.
Summary
Billie Eilish and Justin Bieber have shared live stages at high-profile events, most notably the 2021 Justice tour and 2019 iHeartRadio programming, but they have not released a joint song or formal duet. There are no verified studio collaborations in their discographies as of this writing. While they move in similar pop spheres and occasionally appear together, their musical outputs largely reflect separate creative paths.
