Is Ariana Grande joining Taylor Swift's best friends gang?

The two singers got close following the Victoria's Secret Fashion Show Tuesday evening (Dec. 2), and Swift took to Instagram to document the adventure (which Grande later regrammed). 

Alright ladies, there's still 22 days to surprise-release a Christmas duet. Consider it!
