The reality TV star, 32, showed off her impressive curves in a sexy plunging jumpsuit which clearly made a good impression on West, 35, who couldn't wipe the smile from his face.
It was enough to make him forget about the possible release of a sex tape that is being actively shopped.
The couple was joined by Kim's younger sister Khloé, who had also opted for a fashionable black ensemble which included a military style trench coat and knee high boots.
Older sibling Kourtney and her baby daddy, Scott Disick, had co-ordinated their black pant suits for the meal at upscale eatery Hakkasan in Mayfair, London.
The fashionable group were in good spirits as they left the Chinese restaurant and were whisked away in a waiting limousine.
The raven haired sisters are in the UK to launch their clothing line The Kardashian Kollection.
