Leslie, 29, swapped her well-worn furs for a Malene Oddershede Bach gold and black embroidered full-length gown from the AW16 collection. The metallic piece made the flame-haired Scottish actor a standout on the night, even ahead of everyone's favourite "is he or isn't he dead" GoT hero.

Harington, 29, kept it classic in a black tux with his tousled curls long and gelled, in typical Jon Snow fashion.

Although he said he could "chop off" his hair after his character was stabbed to death and left in a pool of blood at the end of season five, keeping the style he was contractually required to maintain as cast on the HBO drama had prompted speculation he might return to the hit show. (Crazier things have happened, remember that shadow baby?)

Jon, who broke his sacred sex vows with Ygritte in the cave, started talk of a real-life romance in 2012. However, they were rumoured to have split a year later.
