Ariana Grande us having a good week.
And now Grande is posing with Justin Bieber on Instagram, as the latter posted a photo of the pair today and congratulated the singer on her recent success.
"congrats @arianagrande on your number 1 song," Bieber wrote, adding an intriguing tease: "#arianabieberduet??"
Justin and Ariana, of course, are just friends and now, it appears, colleagues.
But there was chatter last summer of something more between the stars after a an image surfaced online of Bieber kissing Grande.
Are you excited for these two to simply work together, though? Ogle pictures of Ariana and sound off now.
