iHeart Radio Festival Las Vegas

Katy Perry was joined on the red carpet by Kelly Rowland and Ashley Greene last night at the iHeart Music Festival inside MGM Grand Garden Arena in Las Vegas. Perry wore her hair in two buns on top of her head and looked lovely in a beautiful, contemporary floral patterned dress and a silver cat choker necklace. Kelly impressed with a striped sweater dress and thigh-high boots, while Ashley showed off her super long, shapely legs in a black dress and heels.
