In case you were wondering, Ariana Grande and Saturday Night Live star Pete Davidson just revealed which Hogwarts houses they're in. Davidson posted an image of them wearing matching Harry Potter costumes, with Davidson wearing the Gryffindor crest and Grande wearing the Slytherin crest.
"The chamber of secrets has been opened…" he captioned the photo. Who says you have to wait until Halloween to play dress up? Grande also continued the Harry Potter theme on her own Instagram, posting a close-up of her Slytherin sweatshirt—just to drive the point home a bit more. Scroll down to see their cute new Instagrams.
