The 2014 iHeartRadio music festival in Las Vegas brought out some of the biggest names in pop music, and with them came some wild fashions and performances.

Taylor Swift rocked a pretty-in-pink two-piece outfit for her performance, though the artist didn't reveal any other new details or songs from her forthcoming new album “1989.”

Ariana Grande might be celebrating Halloween a little early, as she donned little black cat ears with her all-black getup at the MGM Grand Garden Arena event in Las Vegas. She and Nicki Minaj took the stage together to perform certifiable hit “Bang Bang.”

Iggy Azalea looked a little go-go, Coldplay was casual, 5 Seconds Of Summer and One Direction smiled through the (fan) screaming… check out more photos from the weekend event below.
