Ariana Grande References Obscure 'Harry Potter' Spell on Twitter

Even an obliviate curse couldn’t keep Ariana Grande‘s extensive Harry Potter knowledge down.

J.K. Rowling tweeted a picture of an enormous (terrifying) spider this week, and the pop star knew exactly how to respond.

“arania exumai,” Ariana quote-tweeted the author, referencing an obscure spell in Harry Potter and the Chamber of Secrets Hermione uses fighting off spiders.

Fans are seriously impressed with her riddikulus knowledge — but not too surprised.

After all, this is the singer who named her puppy Sirius Black in 2015, and who attended the Deathly Hallows Part II premiere in 2011.

Tell JJJ: What Hogwarts house do you think Ariana would fall in?
