Are Justin Bieber & The Chainsmokers Working On A Collaboration?

Justin Bieber and the Chainsmokers' Drew Taggart & Alex Pall were caught hanging out the other night! So does that mean there is a collaboration in the mix? How cool would that be right?! If this happens I might just lose my cool! Haha

But how did we not know the guy standing next to Justin Bieber when he forgot the words to Despacito was Drew Taggart from Chainsmokers?
