Kylie Jenner's BFF Anastasia 'Stassie' Karanikolaou shows off surgery-enhanced bikini body while swimming with sharks

Anastasia 'Stassie' Karanikolaou shared a series of sexy bikini snaps as well as clips of herself swimming with sharks on Monday.

The social media personality, 27, took to Instagram to show off her mesmerizing beauty and enviable curves in a post, which she simply captioned: 'I [heart] sharks.'

In photos and videos, she was seen flipping her hair as she posed on the beach with clear, crystal blue waters lapping the rocky shoreline. 

She also shared footage of herself wearing the same bikini but this time with a light pink trucker cap on her head as she took a dip in shallow waters with baby sharks circling her. 

Her post comes shortly after she celebrated her best friend Kylie Jenner's 27th birthday on a yacht in the Bahamas over the weekend and after she joined the makeup mogul as well as her two toddlers for a sun-soaked Italian getaway in July.

In snaps from a recent vacation, the influencer modeled a twisted bra top with thin halter straps. 

She also wore a body chain very low on her hips and layered underneath her cheeky bikini bottoms. 

Her dark brunette tresses were down in beach waves, wet from swimming, and her skin was glowing and radiant after soaking up the sun.

She also appeared to be wearing little to no makeup as she showcased her beauty.

She accessorized with a dainty bellybutton ring, a gold pendant necklace and layers of beaded bracelets on her wrist. 

In her striking photo series, she also included a snap of herself sitting on the edge of a boat and laughing so hard that she spit out her best friend Jenner's seltzer and held a can of Sprinter. 

She was seen wearing the same bikini and with her hair tied up in a messy bun as well as sporting a pair of sunglasses with rose-tinted lenses. 

She also shared a clip on her Instagram Story of herself swimming alongside the sharks and petting them as they passed by her.

Karanikolaou also reposted a snap of her and Jenner sitting aboard a yacht, playing poker at a table and twinning in matching outfits. 

The pair also recently were featured in each other's mukbang TikTok videos, in which they indulged on wings and cookies. 

The longtime pals first met through mutual friends when they were 13 and hanging out at a book store, Karanikolaou revealed on an episode of the Call Her Daddy podcast released in 2022. 

Since then, they have remained close and constant friends through their steady rise to fame. When Jenner celebrated her 27th birthday over the weekend, Karanikolaou was present to party with her and was even featured on her Instagram post declaring that she had the 'best birthday ever.' 

During the same podcast appearance, Karanikolaou also got candid about getting plastic surgery at a young age. 

She opened up about the specific procedures she's had done but denied getting any work done on her backside. 

'I have not had butt implants. The only implants that I have are in my t*tties,' she said. 'And I'm not saying that I haven't done other things and I haven't, you know, moved some things around or whatever the case may be. But I just feel like I was at a point in my life when I was younger and I felt like my lips needed to be big, my boobs needed to be big. Everything ... my butt needed to be big.' 

About her decision to get candid, she also stressed the importance of being open about cosmetic enhancements.

In her striking photo series, she also included a snap of herself sitting on the edge of a boat and laughing so hard that she spit out her best friend's seltzer and held a can of Sprinter.

'There's such a stigma in plastic surgery and I feel like whether you say that you've done it or whether you don't say you've done it, people are going to find a way to say something about it and like make it a negative thing,' she said. 'No one needs to tell anyone anything if they don't want to.'

However, she continued to open up about the 'taboo' subject and explained that the very first procedure she had was lip filler — but 'not at a good place,' she said.

Since then, she said she continues to receive negative comments about her appearance on social media and even once in real life when she was vacationing in Greece. 

When a stranger told her she was 'full of plastic,' she said it upset her. 'I wanted to start crying,' she said. 'I don't want to look plastic. I don't want to look fake.' 

Afterwards, she said that she started revising her work to look 'more natural.' 

She also mentioned beauty standards and how they change like trends but noted that she has no regrets even though she wants a different look nowadays. 

'I wouldn't say regret. I would say I've gotten stuff done that I didn't like the result but not regret," she said. 'At the time I wanted it and for the time I liked it. But I have taken it back.'
