Are justin bieber and ariana grande hooking up?

Justin Bieber has been logging lots of studio time lately with everyone from Lil Wayne, to Madison Beer and Austin Mahone.

But on Thursday night he blew our minds when he posted a pic of himself in the studio with Ariana Grande and teased a possible collabo with the singer. “congrats @arianagrande on your number 1 song,” he wrote of her #1 iTunes smash “Problem.”

#arianabieberduet? Yes, make it a thing.
