We had all listened to their number one song and we pretty much liked it and for sure we've already watched its video that has lyrics on the screen for us to memorize the whole song. But what really killed the song is its "official video".

In this video, Halsey really looked so amazing as usual, and had rocked several  different haircuts fo the said video. The ChainSmokers' Andrew Taggart looks so pretty hot too but let us not forget all the things that he claimed he didn't say on twitter. Well, supposedly, Andrew Taggart and Alex Pall together with Halsey and Lady Gaga were feuding over some not so nice comments from Andrew Taggart and Alex Pall.
