Billie Eilish Posts Epic Justin Bieber Fangirl Throwback Photos

Billie Eilish was once just like millions of other fans obsessed with Justin Bieber.

Fresh off joining Bieber onstage at Coachella on Saturday, April 18, the Grammy winner shared a hilarious and nostalgic collection of throwback photos from her self-proclaimed fangirl era.

"Don’t talk to me," Eilish captioned the Instagram post shared Thursday, April 23. The carousel opened with a young Eilish posing in her bedroom, which was completely covered in Bieber posters. Notably, the songstress was wearing a rainbow sequin dress and white Converse, looking every bit the dedicated superfan.

Another slide featured a whiteboard where Eilish rewrote Aqua's "Barbie Girl" lyrics into a full-on Bieber anthem: "I’m a Bieber girl, in a Bieber world, it’s Biebertastic, let’s Bieber blast it, Bieber flips his hair, wears purple everywhere, it’s a Bieber nation, thank god for his creation! Come on Bieber spread the FEVER!"

Other photos showed Eilish wearing Bieber merch over the years, plus old Bieber-themed memes and an epic birthday tribute to the pop icon. The final clip featured a younger Eilish dancing to Bieber's 2013 track "Confident."

Fans loved the post, with many fellow "Beliebers" finding it extremely relatable.



"Biggest belieber ever 🫶🏻," one wrote in the comments, while another said, "we would've been besties af back then."

A third replied, "I'm gonna die, my heart is exploding 😭 that's sooooo cute and sweet."



Others pointed out that Eilish now inspires the same kind of devotion she once had for Bieber.

"That's how I feel about you btw," stated a fan. "This is exactly how we act about you btw," another wrote.

The post came just days after the full-circle moment at Coachella, where Bieber invited Eilish onstage during his performance of the fan-favorite hit "One Less Lonely Girl."

And Eilish later admitted the moment hit her hard emotionally. The day after the performance, she posted a tearful selfie to Instagram Stories and wrote, "Can’t stop crying."
