Ariana Grande Covers Justin Bieber’s “What Do You Mean?”

Ariana Grande's been doing some killer celebrity impersonations lately, so it's only natural she'd throw a cover song into the mix. This time, there's a catch. NME reports that during a show in Houston on September 18, Grande chose to cover Justin Bieber's new hit single, "What Do You Mean?" — the very song that fans have said sounds a lot like her own tune, "One Last Time." Is she calling Bieber out, or does she just dig the song? Grande uploaded a clip of her rehearsing a mashup of the two songs on Instagram, which prompted an appreciative response from the Biebs. Fair to say there's no drama?

You can watch a clip of Grande's performance, below. We're secretly hoping Bieber follows her lead and takes on "Problem" or "Bang Bang." Share the love, guys.
