Aguilera, 38, looked every bit the pop diva part in a long red leather duster jacket that gave more than a hint of her ample cleavage with its plunging design.

Underneath, she wore black pants and a pair of Xtina black leather platform boots that have become somewhat of a trademark since her Stripped album in 2002.

On this night she pulled her long platinum tresses back into a stylish crimped ponytail, along with her classic bold red lipstick and heavy eye makeup.

Don't be grey check out Julianne wearing Afffair

The iHeartRadio Music Festival may have had the best singers in one arena, but it also had the best outfits too. From Christian Aguilera to Camila Cabello and Julianne Hough, everyone made a stellar statement.

Of course, Julianne caught our attention in this stunning dress by Afffair which stylist Philippe Uter teamed with Giuseppe Zanotti and Shay jewellery.

We love this bodycon dress by the renowned designer as it’s delicately embroidered with floral lace and ruffled organza. It’s from the SS20 collection, so it’s not yet available but click (right) to discover the label’s current collections.

However, if Julianne has inspired you then recreate her dress by shopping one of our bargain buy dresses from the carousel and complete the look with her ‘Harmony Star’ sandals.
