Rihanna impressed at the GQ Men Of The Year party at Chateau Marmont in Los Angeles last night, taking to the red carpet in a slinky slip dress.

The Barbadian singer chose a simple firebox red strappy dress for the event, which was attended by a selection of Hollywood's biggest stars.

She accessorised the mini-dress with a pair of red strappy heels, wearing her hair slicked back into a ponytail. She finished off the look with a slick of classic scarlet lipstick and elegant, smokey eye makeup.

Also in attendance was actress Diane Kruger, who went for an edgier look in an unusual cream dress, which was slashed at the middle and held together with a braid which looped around her neck.

She counteracted the midriff-exposing dress by wearing a black tuxedo jacket draped around her shoulders.

The Inglorious Basterds star accessorised simply with black heels, a clutch back and wore her blonde locks in a loose updo.

Argo star Ben Affleck looked dapper in a charcoal three piece suit and a striped tie.

Breaking Bad's Aaron Paul went for a slightly more unusual suit, wearing a grey suit speckled with white, pairing it with a slim tie and white shirt.

Actress Camilla Belle looked chic in a unusual cut navy and white dress, which featured sheer panels and an asymmetric hemline.

True Blood star Stephen Moyer kept it simple in a two-piece suit with a black, unbuttoned shirt underneath.
