In yet another promo spot, this one with this week’s musical guestJustin Timberlake, Johnson wore a little black dress — but it was anything but basic. The sleeveless minidress, much like her look for her monologue on Saturday night, featured a dramatic cutout across her chest, offering a racy peek at her skin.
