BTS is right now in Las Vegas, just less than hour away from going to the Red Carper for the 2017 Billboard Music Awards.
The Chainsmokers had an opportunity to meet BTS and they recently dropped a post that seems to hint that a summer collaboration​ may be happening. It has yet not been confirmed but the following post from The Chainsmokers seems to give everyone a lot of excitement just thinking BTS will be collabing with a large American artist.
More details will come soon!
