Who is Kylie Jenner's best friend 'Stassie baby' (not her real name)? (2024)

You might have noticed Kylie Jenner has a constant Instagram sidekick: Anastasia Karanikolaou, who also goes by the name Stassie or Stassie Baby on social media.

Jenner took to social media to share a “fun fact” about the pair, who have been friends since childhood. Posing in matching nude corseted bodysuits and sunglasses, Jenner wrote, “we’ve been twinning since we were in middle school. we used to never leave the house unless we had a matching outfit on 🤣😍... so get ready for a lifetime of more twin pics.”

While her Instagram presence might feel like a post-Jordyn Woods turn of events, Jenner and Stassie actually go way back. ​Stassie has known Forbes' youngest self-made billionaire for nine years, with Stassie so close to Kylie Jenner that at one point she even moved into her home.

Stassie is Jenner’s go-to travel buddy and the pair have been everywhere together, from Italy to Turks & Caicos - naturally in matching designer outfits.

The friends have an incredibly close bond and self-isolated together over lockdown, heading to Kris Jenner’s second home in Palm Springs alongside Jenner’s daughter Stormi Webster. Stassie (who Jenner called her "quarantine friend") was also featured in Jenner’s famous pregnancy reveal video and has matching tattoos with Jenner that feature Stormi’s name.

Jenner revealed just how close the pair are in a birthday message for Stassie’s birthday, calling her her “fairy 42 sister.”

She shared a gallery of pictures of the pair in which the pair were seen wearing matching Playboy bunny outfits and Chanel co-ords, adding that Stassie was “the best aunty to my babygirl” Stormi Webster.

Jenner also left her home during California's stay at home order to see her, before it was revealed they were self-isolating in Palm Springs together. They also drew controversy when it was revealed they flouted the order to celebrate Stassie’s 23rd birthday with a group of at least ten people (including Jenner).

Beyond being Jenner's "most consistent and loyal friend", Stassie is also a popular social media influencer and plastic surgery fan, speaking honestly about her procedures on social media. For more on Stassie Baby, read on.

Anastasia Karanikolaou is a model and social media star, who is also known online as Stas, Stassi or Stassie Baby. With over six million Instagram followers and 200,000 YouTube followers, Karanikolaou frequently models outfits for her audience and occasionally vlogs about her life, including one popular video about her entire plastic surgery journey.

The influencer has also recently poured a lot of effort into her TikTok presence, sharing videos of herself and Jenner from lockdown dancing to popular songs on the app. She's also shared TikTok videos alongside Too Hot to Handle star Harry Jowsey, sparking rumours that they're dating.

The Netflix star seemingly confirmed their relationship after posting pictures of the pair.

However, it seems like she's since moved on. She's now said to be dating another Netflix actor, rom-com star Noah Centineo.

While there was no confirmation that she was with Centineo, they were spotted together in Las Vegas and she was even seen posing with a large ring on her finger on Instagram.

She has also worked with brands including PrettyLittleThing and Good American on limited fashion collaborations and campaigns.

She and Jenner have been friends for a very long time, with Jenner revealing on Instagram that the pair’s friendship goes back 9 years.

To celebrate Stassie’s birthday, Jenner shared a picture of the pair and wrote, “9 years later and you’re still a real one. I love you forever and always.”

Kendall Jenner is also close to Stassie and Kylie revealed on Instagram stories that “Stas basically lived with me growing up, and it was the 3 of us always.”

Stassie is also close to Kylie’s former best friend Jordyn Woods, who was excommunicated from the Kardashians after rumours surfaced that Khloe Kardashian’s boyfriend had cheated on her with Woods. Stassie has not posted an image with Woods since October 2018.

Stassie has a pretty packed social calendar - with her friend Kylie as a popular fixture on it. They celebrated Halloween together at a Playboy-themed party, which followed Kylie’s Playboy cover and interview with her now-ex Travis Scott over the summer.

Stassie used to live with Jenner but has since moved out into her own impressive home, although they did quarantine together.

She shared a house tour on her YouTube channel and revealed that she was planning to make significant changes to the house, which included adding a Jacuzzi to the backyard.

At one point, Stassie was rumoured to be dating Bachelorette star Tyler Cameron after they were seen hanging out and partying together. On November 25, Stassie accompanied Cameron (who was previously linked to model Gigi Hadid) to an NFL game alongside Kendall Jenner and other friends.

A source told E! That “Tyler seemed excited to hangout with her and had a huge smile on his face”, as the pair were seen “chatting and laughing”. Later on, they reportedly scooped up Jenner for a big night out at the Nice Guy and Poppy nightclub and “definitely showing PDA.”

“Tyler was holding Stassie at one point and they were dancing. They were chatting the entire night, whispering in each other's ears and Tyler grabbed Stassie's face at one point for a kiss,” they continued.

A source told E! That it’s unlikely it was going to be a long term thing, as they said, “He is only in LA for the next two months and wants to party and hangout with her while he is here. He doesn't want anything serious but is having fun with her.”

She has since seemingly moved on and has been spending time with Australian reality star Harry Jowsey, posting TikToks with him and being photographed around Hollywood.

Stassie’s father is Periklis Nikolaos Karanikolaou, a Greek-born broker for World Financial Group, according to LinkedIn. The pair appear to be close and he has previously featured in vlogs and on her Instagram.

On Father’s Day, she shared a snap of her dad cradling her as a baby and wrote, “thank you for always being there for me when i need you, for showing me unconditional love, for knowing how to cheer me up when i’m sad, and for dealing with my annoying ass on a daily basis. i couldn’t have asked for a better dad. i love you to the moon and back. happy father’s day.”

She also couldn’t resist a sly dig at her father’s expense, as she posted a photo of Periklis sleeping surrounded by booze. She captioned it, “my dad is me”.

Her mother is Nicolette Karanikolaou, who wished Stassie a happy birthday on Instagram. She wrote, “You are such an amazing young woman with a beautiful life ahead. I wish you only success and happiness in your life and I am so thankful that life brought us together.”

It appears that Nicolette may not Stassie’s biological mother but rather a stepmother, as in a birthday post addressed to Periklis, she wrote, “i know the last years have been challenging for you and we are journeying together onto new territory’s [sic] and watching your girls and my son’s grow! #blendedfamily Thank you for being open to live and love again.”

Stassie also has a sister named Alexia Karanikolaou, who works as a hairstylist and also features regularly on her Instagram.

Stassie has been incredibly open about her experience with plastic surgery and has revealed over the past few years that she has had two breast augmentations. They were both done by celebrity plastic surgeon Dr Ashkan Ghavami, who is also the man behind Iggy Azalea’s breast and nose procedures.

She and Ghavami spoke candidly to Harper’s Bazaar about her first procedure. It turns out that one of Stassie’s breasts was nearly a full cup size up than the other one, which made it difficult to find bras that fit.

Following the procedure, Stassie told Harper’s Bazaar, “I was very open to sharing—plastic surgery is nothing be ashamed of. A lot of people think plastic surgery is only for cosmetic reasons, to change something you're insecure about.”

She continued, “All my comments were saying, 'you're so insecure, you're so insecure,' which is the complete opposite. If I was insecure, I wouldn't have showed it. I wanted to show people that there's nothing to be ashamed of— that it's so common for girls to have this issue and you can do something to fix it.”

After her first breast augmentation, Stassie had another one in the same year to increase the size of her breasts. In fact, she even shared an entire 15 minute vlog about her experience which takes her YouTube audience into her consultations with Dr. Ghavami and through the process behind it.

She explained her reasoning behind the surgery, saying, “When I lost all my weight, [my boobs] just like shrunk. And I just want them to be like cute again. I don’t know. Judge me if you wish.”

At the end of the video, she showed off her new chest at a post-op appointment with Dr Ghavemi.

Stassie has also been open about the fact that she uses lip fillers.

While Stassie’s exact net worth isn’t known, her massive social media following has netted her a few lucrative brand sponsorships. She's also worked with a number of swimwear brands including White Fox Swim, Elise x Elisia, Hoaka Swimwear and designers Oh Polly and Showpo.

A source told Entertainment Tonight that Stassie “won’t post anything on Twitter or Instagram for less than $5,000”.

However given that the source said this back in 2015, her rate has probably increased since then - especially since she now boasts an Instagram following of over six million.

The star also revealed that she had moved into a new home in February in a sponsored YouTube video. It was not clear if she had purchased the four bedroom home, but she revealed she was making big changes to it including changing out chandeliers, adding a Jacuzzi and repainting various rooms.

Stassie is now 23, as of June 9.

She celebrated in style, with her best friend Jenner throwing her a major birthday extravaganza. From a questionable The Handmaid’s Tale-themed viewing party to some poolside antics in matching pink bikinis, she and Kylie have spent the past few days together, which culminated in the pair attempting to play golf in matching Chanel outfits.

Jenner and Karanikolaou have previously talked about how the pair became close friends. On Stassie’s birthday, Jenner shared a series of Instagram stories detailing their nine year friendship - but it began just before the pair were attached at the hip.

Jenner explained, “So it all started when I met a beautiful bomb ass blonde at Barnes and Nobles.”

According to Page Six, they met at the bookstore when Stassie attended a fan event Jenner was part of. Following that, Stassie became a close friend of the family and spent a lot of time with her before moving into a shared house with Jenner and her formerly close friend Jordyn Woods.

In an interview with Teen Vogue, Jenner said, "You’ve been the most consistent and loyal friend in my life, and I feel like without you, I wouldn’t be the person I am today. Because I wouldn’t be weird anymore. I’d be trying to be normal."
