In a tweet fired off early Monday morning, the [_Dangerous Woman_ singer](http://time.com/4308929/ariana-grande-dangerous-woman-time-100/) responded to a recent update from author J.K. Rowling, using a rare only-seen-in-movies spell. It all started when Rowling shared a photo of a giant spider that she recently encountered. “I am a strong, independent woman. Also, thanks very much to my husband for dealing with this so I could go through the door it was blocking,” she joked in the tweet. (Warning: arachnophobes, look away now.) Seems like Rowling shares at least one trait in common with Ron Weasley. > [](https://twitter.com/jk%5Frowling/status/909671414499827712) But Grande has the perfect answer to all of Rowling’s troubles — assuming, of course, that at least one of them is a witch. “Arania exumai,” she tweeted back at Rowling. Potter movie addicts will recall that this is the incantation used in the movie version of _Harry Potter and the Chamber of Secrets_ when Harry and Ron venture into the dangerous territory of a tribe of [giant venomous acromantulas](https://www.youtube.com/watch?v=-64vAnXnoW0) in the Forbidden Forest. > [](https://twitter.com/ArianaGrande/status/909695481235767296) This isn’t the first time Grande has shown off her love for Rowling’s magical world, though.
