The 28-year-old actor looked handsome in a black, velvet blazer as the 51-year-old director rocked a black dress for the event.
Also stepping out for the event was designer Tom Ford – who directed Aaron in the 2016 film Nocturnal Animals.
FYI: Aaron is wearing a Tom Ford tux. Tom is also wearing a tux of his own design.
