Even global superstars have their fangirl moments, and Billie Eilish just proved it again. After being pulled onstage by Justin Bieber during his recent Coachella performance, Eilish took a trip down memory lane, sharing throwback photos that highlight just how deep her Belieber phase really went. The singer posted a series of childhood images showing her bedroom covered in Bieber posters, along with old fan messages that read like something straight out of peak 2010s fandom culture.
One standout photo featured a whiteboard filled with playful lyrics inspired by Aqua’s Barbie World, rewritten entirely around Bieber. It was not just casual admiration either. The posts made it clear that Eilish was fully invested, from wearing Bieber merch to writing emotional notes about how much she loved him. In one message, she even called him “the best singer and person in the world,” capturing that intense, all consuming energy that comes with being a teenage fan.
The full circle moment came when Bieber brought her onstage for his classic One Less Lonely Girl segment. Eilish, who was in the crowd with Hailey Bieber and her brother’s fiancée, looked genuinely overwhelmed as she hugged him and got emotional during the performance.
What makes this story land is how relatable it feels despite the scale. It is easy to forget that before the Grammys, Oscars, and global tours, artists like Eilish were just fans themselves. That kind of authenticity is rare in an industry that often feels overly polished.
At the same time, moments like this also show how powerful early fandom can be. Bieber was not just a favorite artist for her, he was clearly a formative influence. Seeing that connection come full circle onstage years later is the kind of narrative pop culture thrives on.
It is also a reminder that no matter how famous someone becomes, that first artist you truly loved never really loses their place.
