iHeart Radio Awards 2016: The best red-carpet looks

Taylor Swift
The Shake it Off singer looked amazing and oozed sassiness in a black sequined catsuit.

Selena Gomez
Selena showed off her enviable figure in a summery orange jumpsuit, with strategic slits revealing her toned stomach.

Demi Lovato
Former X Factor USA judge Demi opted for a tailored look in a black and whte trouser suit, and kept her hair and make-up simple and chic.

Iggy Azalea
Iggy took her rap attitude to the red carpet with a branded crop top and baggy blue trousers - her dark lip complimented the look perfectly.

Julianne Hough
We love Julianne's cute white halterneck, and the flower detailing is perfect for spring.

Karrueche Tran
Chris Brown's on/off girlfriend added a feminine touch to her coral leather mini dress with fluffy shoulder embelishments.

Keke Palmer
Singer Keke got it so right in a sequined blue halterneck dress, and we love her purple lip and yellow manicure.

Kelly Osbourne
Kelly means business in a black zip-up dress, but her pale lilac hair totally stole the show.
