So, there are A LOT of proper celebs in this round-up. 1D! Demi! Hailee Steinfeld! Cher Horowitz! You know it’s the end of the year when I’m all, “Harry Styles is dressed as a powder room, whatever. Let’s move on!” (Which, for what it’s worth, seemed to be how Harry felt on the red carpet, although he did seem really interested in chasing down Gigi Hadid, which…those two are totally going to date. As old and boring as I am now, I do thrill to the amount of ex and possibly future couples there were in attendance at this event. Take T Swift’s girl squad and place them in a room with a variety of Jonaii and watch what happens.)
