In a match made in Scooter Braun's idea of heaven, Justin Bieber and Ariana Grande are flirting on Twitter.

Bieber and Grande are currently on the boy wonder's Believe Tour and share a manager in Braun, and what better way to promote their shows together than to insinuate that you're hooking up?

The duo's exchange began when Grande posted the below photo of her grandparents with Bieber, gushing about how much her grandma loves the Canadian heartthrob.

Bieber responded by requesting that Grande post another photo:

And she totally did, and we bet Selena Gomez is really jealous:

Still, it may be an innocuous, friendly peck on the cheek, because Grande's taken (she's been dating Australian would-be comedian Jai Brooks for about 10 months) -- and because someone close to her has her eyes on Biebs.
