If there's one thing that unites young and old; famous and mere muggle, it's a love of Harry Potter.
There's just something about the wizardly franchise that transcends all boundaries.
Even huge music stars like Billie Eilish aren't too cool to fangirl over Harry Potter—and there are pics to prove it!
Last week, Billie and her older brother Finneas went to see the Harry Potter and the Cursed Child Broadway play in New York City.
Watch: How Billie Eilish walked on the walls and ceiling during this live performance may actually blow your mind...
Not only did they go in theme (Billie rocked a Slytherin-inspired jumpsuit and a wand) but they also posed with the entire cast—and the pics are absolutely adorable
The 17-year-old could barely wipe the smile off her face as she cuddled with the broadway stars and honestly—it might actually be the happiest we've ever seen her!
Clearly, the feeling was mutual, because the IG account of the Cursed Child gave Billie a shout-out, too.
"She’s that magic type, go to #CursedChildNYC type - duh. We loved having you @billieeilish and @finneas," they posted in the caption.
It's quite funny, because Billie is notoriously quite a tough nut to crack.
Not only does she seem utterly unfazed meeting huge celebs like Justin Bieber, but she's also the girl who unfollowed Tana Mongeau and left the Shawn Mendes on read.
So, to see her nerd out over something like Harry Potter is actually super sweet.
You can see the rest of the cute pics here.
