But it was our fave reality TV queen who stole the show (obvs!) by wearing a low-cut dress slashed down to her waist at the birthday bash.
Just about covering her modesty, the white grecian-style dress shows off Kim's ample assets to perfection.
Kim slicked her hair back for her big night at TAO nightclub in Vegas and opted for relatively pared back make-up to let her dress do the talking.
Cut low at the back as well as the front, her white dress managed to remain chic thanks to its mid-calf length.
Kim partied the night away with her family, hubby Kanye West, BFF Jonathan Cheban and a whole host of besties at the celebrity nightspot.
On Saturday (25 October) Kim shared various snaps of the evening, including one of her posing with her styling squad.
Kim said: "My Glam Gods for the night @jenatkinhair @makeupbymario."
In another pic, she added: "Vega$ Nights have begun."
Earlier on Friday, she shared a picture of her and her faves getting ready to jet to the party city.
Kim and hubby Kanye posed outside what looks very much like their own private jet, along with momager Kris Jenner and other members of Kim's inner circle.
LOVE that Kim's idea of an airport outfit involves nude trousers and an oversized blazer, btw.
Kim simply said: "VEGA$"
The TV superstar, who turned 34 on 21 October, has been a busy birthday girl of late. Romantic Kanye whisked her off for a mini break in Hawaii and Kim's been inundated with birthday wishes.
She said: "Thank you so much for all of the birthday messages!!!!! I'm so grateful to be celebrating another year & to feel all of this love!"
