Anastasia “Stassie” Karanikolaou celebrated her 24th birthday this week with her famous best friend, Kylie Jenner.
Karanikolaou has been best pals with the Keeping Up With the Kardashians star since Jenner fell out with Jordyn Woods in 2019. The billionaire and the social media influencer have been close pals for several years and had plastic surgeries together.
And on Tuesday, she marked her 24th birthday by hosting a joint party with Zack Bia, where they invited the stars to join them at Goya Studios Hollywood for the evening.
Wearing a stunning and completely sheer silver gown, Karanikolaou commanded attention.
Karanikolaou showed off her impressive surgically-enhanced figure but protected some of her modesty by wearing a nude thong and strapless bra underneath her sheer dress.
She has been very open about going under the knife to transform her body.
Talking about her boob job, she said: “When I lost all my weight, [my boobs] just like shrunk…And I just want them to be like cute again. Whatever. Judge me if you wish.”
In videos on Kylie Jenner’s Instagram Stories from the night, her 239 million followers got a glimpse of the food available for guests, which was neatly laid out on a long table with wine glasses, white flowers, and candles.
Jenner was wearing a tiger print outfit and drove to the venue, covering her face with one hand while sitting in the car as she arrived.
Other celebrities included Hailey Bieber, Winnie Harlow, and Jenner’s sister, Kendall Jenner.
Video clips on Jenner’s story also showed Karanikolaou blowing out several candles on a large white cake; Travis Scott‘s baby mama could be heard from behind the camera telling her best friend to “make a wish.”
The birthday girl had a low-key celebration at one of Kylie Jenner’s mansions. In one of the clips, the party-goers said they had to whisper because Kylie Jenner’s daughter, Stormi Webster, was sleeping in the next room.
A final snap was of Karanikolaou twerking and shaking her large and toned behind in a car park, standing next to a car.
More celebrations had taken place the night before, with Karanikolaou seen on Monday wearing a sequined bralette and sheer skirt as she partied with pals ahead of her birthday.
She has known Kylie Jenner since the pair was ten years old but only became best friends more recently when the beauty maven fell out with Jordyn Woods.
Now Jenner and Karanikolaou are often seen on each other’s social media pages, famously wearing coordinating — or even matching — outfits.
The friends have a habit of making tongues wag by sharing kisses and by playing touchy with each other.
