In the masquerade house party above, the singer/actress wears over-the-top dresses and cools herself with a regal hand fan, while the Detroit MC decks himself out as a fly priest. It ends with a steamy pool makeout session between Grande and her music video's love interest.
Cool costumes? House party? Pool makeout session? Yup, sounds like the perfect Halloween to us.
While the duo rocked excellent costumes in the video, check out Fifth Harmony, Adam Levine, Kanye West and more freakishly fantastic celeb Halloween costumes here.
