In a nod to their upcoming wedding, the glamorous star sported a bridal-esque, off-white strapless gown while Kanye, 36, is seen standing behind her with his arms around her waist, nuzzling into her neck.
In recent weeks focus has been on Kim and Kanye's actual nuptials, with reports circulating that she has picked her wedding dress.
While some have speculated that the enormous Balmain shopping bag could be to do with her outfit for Anna's forthcoming Met Ball, others have said it hints she has settled on the French fashion house to design her wedding gown.
