Jessica Biel stunned in a Marchesa prom-style gown at the premiere of her husband Justin Timberlake's latest film Inside Llewyn Davis at Cannes.
The actress chose a strapless, mid-length dove grey evening dress which featured a feather underskirt and textured appliqué detailing.
Biel chose a serpent necklace, studded clutch bag and a pair of pointed slingback sandals to wear with the unusual gown, which was from Marchesa's autumn 2012 collection.
Timberlake posed on the red carpet alongside his co-star Carey Mulligan, who looked chic in a flowing monochrome Vionnet dress. The gown featured risqué cut-out detailing at the bust and a split up the skirt.
