The rapper boldly grabbed his wife's most famous asset on Saturday night (27 September), just in time for a photo to be taken - good timing, Kanye!
But luckily Kim saw the funny side and posted the cheeky snap on her official Instagram account.
In the picture, Kanye and Kim can be seen from behind walking down some elegant stairs, with Kanye in his Yeezus T-shirt (of course!) and Kim in a super tight outfit (natch!).
Seeing as Kim's bum is a celebrity in its own right, we're not surprised Kanye is rather fond of it.
Kimye are currently in Paris for Fashion Week and Kim has become rather partial to a super tight nude bodysuit. As well as teaming it with a pencil skirt for the bum shot, she also wore it with pedal pushers earlier this week!
Luckily, she seems to have fully recovered from a rather scary encounter with a prankster, who attempted to grab her legs and pull her to the ground.
While in Paris, Kim has been spotted buying designer baby clothes for daughter North, and sitting in the FROW to support her sister Kendall Jenner during the Balmain show.
Kim and Kanye even took their daughter North to the Balanciaga show. The toddler was seen tottering into the venue in leather trousers and heavy duty boots, before sitting on her mum's knee to watch the show.
We wonder what North thought of it all?!
