Wow. That’s all we have to say about Ariana Grande’s cover of Justin Bieber’s song, “Die in Your Arms,” from his new album, Believe. Not only did Ariana manage to create a pretty awesome music video, but her vocals are totally amaze, too! She even took the time to change some of the lyrics to make them more girl-friendly — it was almost like she was singing a response to JB! Hmmm, could this be the beginning of an Justana duet? Lucky for Ari, Justin not only heard the song, but he was also blown away by her rendition! So. Cool. Check out their Twitter convo and then watch the video above!
