As Caitlyn Jenner welcomes another year to her blissful life, she made sure she spent her birthday with everyone close to her heart-- including the Kardashians.

Caitlyn Jenner celebrated her 70th birthday at Nobu in Malibu on Tuesday this week. The celebrity invited her two daughters, Kendall and Kylie Jenner, and her step-daughters Kim and Kourtney Kardashian.

Kim, being Kim, was seen leaving the birthday celebration wearing a flared snakeskin trouser with a fit-grey bodysuit, which left everyone absolutely stunned.

The 39-year old "Keeping Up With The Kardashians" star showed her flat stomach to the public with her bodysuit hugging her shape perfectly.

Her skintight look -- a high-neck, long-sleeve grey coloured bodysuit paired with a gorgeous patterned bottom -- made her look like an absolute body-goal icon. The snakeskin trousers were fitted at her waist part, which hugged her signature Kim Kardashian hips. The trouser's hemline was topped off with a drawstring that added a fabulous accent to the whole body look.

The mom-of-four topped off her look with a suede beige coat and strappy nude-coloured heels. She also styled her dark long hair in wavy lengths and finished her look by wearing smokey eye makeup and light pink lipstick.

What About the Other Kardashians?

Kourtney Kardashian, meanwhile, went for an all-black attire in the celebration. The 40-year-old reality TV star wore black trousers and paired it with a black top. She wore a pair of pointed black boots and finished her night look with a brown, mini Louis Vuitton handbag.

Self-made billionaire and Kylie Cosmetics owner Kylie Jenner also flashed her way at Caitlyn's birthday celebration with a black turtleneck top with matching bottoms and a Hermes Birkin bag. Just like Kim, she also had her hair on long tresses loose.

The birthday celebrant, Caitlyn, went for an ankle-grazing black and white accent maxi skirt with a dark long-sleeve top. She paired her look with some classic pumps.

Caitlyn invited some of her close friends and family to a birthday dinner on Tuesday to celebrate her 70 years of life. The former Olympian invited her daughters Kendall and Kylie, her son Brandon, and step-daughters Kourtney and Kim. However, Caitlyn's other son Brody Jenner and step-daughter Khloe Kardashian were not seen on the event.

During her birthday dinner, a throwback photo of her time as Bruce was showed. The picture showed the then-Bruce Jenner holding his two daughters Kendall and Kylie.

The birthday celebrant seemed to enjoy the night based on Kourtney and Kim's Instagram stories, where it showed a clip of her happily blowing her birthday candles between Brandon and Kylie.
