The country singer changed out of her strapless Nicolas Jebran gown and into a pretty pleated Maria Lucia Hohan dress for her duet with breakthrough artist Sam Hunt. 

The star topped off her slinky black skirt with a sharp double-breasted blazer (sans layers) by Norisol Ferrari on the red carpet. For the stage, she continued the same aesthetic with a sleek optic white blazer and tailored trousers by Alexander McQueen. 

The All About That Bass singer worked her curves on the red carpet in a slinky shimmering gown—a look that she continued to rock for her on-stage performance. The only differences? Leather lapels and an abbreviated hem.

The Grammy Award nominee upped the glam factor for her red carpet stroll in a sculpted one-shoulder emerald green Gauri & Nainika creation. But for her performance, she reverted back to her casual-cool uniform, featuring a black moto jacket layered over a printed Thomas Wylde top and black skinnies.

Talk about a complete 180! The singer was perfectly sweet in a minimalist custom rose quartz Stella McCartney gown and then completely sexy in a beaded see-through black number moments later.

Adele knows what she likes. She remained loyal to her go-to fit-and-flared silhouette, switching from one flattering custom Givenchy Haute Couture by Riccardo Tisci design to another. 

The Biebs was dapper in his sleek black separates on the red carpet. But for his upbeat performance for "Where Are U Now" and "Love Yourself," he aimed for comfort with casual black separates and a leopard-print bomber.

For her tribute to the rock 'n roll legend that is David Bowie, Lady Gaga went all out—first in a custom embroidered Marc Jacobs double-breasted creation and then later in a sparkle-encrusted white jumpsuit, complete with an oversize pale pink fur stole.
