Well, aren't these two very different looks? Christina Aguilera headed to the Madrid premiere of Burlesque in a red lacy D&G dress. She accessorised with a wide belt, opaque tights, black courts and her usual full-on makeup.

Isla Fisher wore the same dress for the Burke and Hare premiere in London, opting instead for a more natural look, while also ditching the belt and going for sheer tights. We like!

But between the two of them, who do you think wore D&G better? Christina or Isla? It's a tough call, we know...
