Looking fabulous in monochrome, the reality star stole the show at the glitzy bash held at private members club Annabel's on Wednesday evening (3 September).
Kim, 33, showed off her figure (as per usual!) in a plunging, fitted black leather peplum top with white detailing, teamed with a super-tight leather pencil skirt and nude heels.
It was the same colour combination she'd worn earlier in the day when she visited the BBC Radio 1 studios in a gorgeous monochrome jumpsuit.
Kim jetted into London on Tuesday with husband Kanye West but he wasn't in attendance at yesterday's party. Instead, the rapper has jetted off to Australia to prepare for his upcoming tour of the country.
Kim and the couple's one-year-old daughter North West will fly to Oz themselves later today.
Instead, Kim cosied up to model Liberty Ross at yesterday's event, which celebrated her Genetic x Liberty Ross fashion collection. Kim was also seen hanging out with Liberty in September last year when she and Kanye attended the model's birthday party in September.
Liberty is dating music mogul Jimmy Iovine. She was previously married to director Rupert Sanders but filed for divorce after he was caught cheating on her with actress Kristen Stewart.
The reason for Kim's visit to London this week was to attend the GQ Men of the Year Awards on Tuesday night, where she picked up the prize for 'Woman of the Year'.
Explaining her win, GQ said: "It wouldn't be wrong to claim that, right now, she's the most famous woman in the world. Even Obama talks about her. It wouldn't be wrong, either, to say she's redefined the meaning of pop culture in the mere space of 12 months."
And Kim was VERY happy!
"What a huge honour to win Woman of the Year," she said. "It's so special. I want to thank my husband for making me feel like the Woman of the Year every single day."
Kim also found time to visit the BBC Radio 1 Breakfast Show the following morning where she revealed, among other things, that she has a MASSIVE obsession with eating ribs, she absolutely LOVES singer Sam Smith and she so DOESN'T care if you forget to add her married name West to the end of her surname.
