It was the battle of the black dress last night as Jen opted for a strapless chiffon Dolce & Gabbana number, which she paired with a grey Burberry clutch and Fred Leighton jewellery.
Nicole, meanwhile, went for a different take on black in a leather jacket and pencil skirt combination by L'Wren Scott, which she finished with a blush-pink scarf and big hair.
They were joined by their co-stars Adam Sandler and Brooklyn Decker, who walked on the wild side in a revealing leopard-print number.
So what do you prefer... Nicole's fashion-forward look? Or Jen's soft, feminine frock?
