From the very casual, looking at you Chris Brown, to the cliché, Usher, all sorts of fashions walked the red carpet on day one of music love fest (all of which are viewable in the photo gallery above).
If there were an award for best dressed to be handed out though, our vote would go to The Walking Dead starlet Emily Kinney. The girl most known as her role of Beth on the zombie drama looked fan-effing-tastic in her blue jumpsuit and stood out in the crowd of A and B-list celebrities.
If you’re in the mood to catch even more music tonight, the whole event is being streamed online beginning at 10 pm Eastern on the official iHeartRadio website. Today’s lineup includes One Direction, Iggy Azalea, Lorde, Paramore, Ed Sheeran and Calvin Harris to name a few.
