The reality star, 31, wore a jaw-dropping gold-and-cream Balmain dress with a plunging neckline and super-short hem, paired with sexy ankle boots. (The frock has already been worn by Katy Perry, Zoe Saldana and other stars.) West, 34, complemented his love of nearly three months in a white shirt, cream jacket, denim and black loafers.
According to a source, the couple "were inseparable" at the afterparty for Cruel Summer, one of the first projects of West's Donda creative firm. The twosome were "kissing in the back the whole time." (West's buddy Jay Z, sans wife Beyonce, showed up to support his frequent collaborator.)
