The curvaceous reality TV regular was a guest on a special episode of The Tonight Show yesterday evening (17 February), which marked Jimmy Fallon's first appearance as host.
But she wasn't the only A-lister in the building, as Jimmy roped in a plethora of famous faces to help mark his debut on the late night talk show.
Joining Kim were Hollywood actors Robert DeNiro, Will Smith, Sarah Jessica Parker and Lindsay Lohan, comedians Seth Rogen and Tracy Morgan, retired professional boxer Mike Tyson, singers Mariah Carey and Lady Gaga and that wasn't it!
Making the most of her star studded surroundings, Kim crammed as many of the celebs into a photo, which she then posted on Instagram.
Surprisingly though, the 33-year-old brunette wasn't the most flamboyantly dressed on the evening and decided to opt for a rather simple outfit.
Lady Gaga made quite an impression (as always!) on the show by sporting a revealing black one-piece made of netting and some giant platform heels.
Meanwhile, Sarah Jessica also upped the glam factor in a gorgeous white floral frock.
With everyone else making such an effort, it's a little surprising to see the Kardashian star in such a laid back look.
Earlier in the day, Kim had been seen out in New York wearing an unflattering leather maxi dress.
But proving that she has an endless supply of clothes even when away from her LA home, Kim decided to change into a pair of black jeans and a white shirt for The Tonight Show.
During her time backstage, the mother-of-one grabbed comedians Seth and Tracy for an Instagram photo and noted that she was having "fun behind the scenes pic with these funny guys."
But this isn't the first time she has spoken to Seth.
Last year Kim applauded the Superbad actor on his spoof of Kanye West's 'Bound 2' music video, which he made with fellow actor and best friend James Franco.
The two men mocked Kanye and fiancée Kim's display of affection in the visual, much to everyone's amusement - including KimYe's!
Speaking about the parody last November, Kim tweeted Seth: "Kanye says what's up! He loves u guys! He laughed so hard at this."
