Kylie Jenner’s best friend Anastasia ‘Stassie’ Karanikolaou sizzled up a storm on Sunday, as she shared a new snap of herself modeling lingerie. 

The Instagram model, 26, put her hourglass curves on display in a black Lounge Underwear set that highlighted her ample cleavage and flat tummy.

The beauty — who recently enjoyed an outing with Kylie — was seen lounging in bed, partially covered by a blanket in the sultry snap.

Her brunette hair cascaded down in loose waves, and the star wore picture-perfect glam for the snap.

‘Happiiiii sunday,’ she captioned the post, adding a white-heart emoji.

Her 10.5M followers were thrilled with the offering, with one commenting, ‘gorgeoussss.’

‘Happy sunday queen,’ another added.

Earlier this week Stassie shared a snap with her bestie Kylie, 26, after she supported the lipkit mogul at her Sprinter brand launch party on Thursday. The pair posed at the event with their friend Carter Gregory.

Stassie turned heads in a sheer off-shoulder black dress under which she went braless. The sultry garment clung to her formidable figure and left little to the imagination, showing off her black underwear and belly button piercing.

The star — who has previously admitted to having a string of surgical enhancements — added height to her frame with a pair of pointed-toe black heels.

Stassie, who is of Greek descent, wore her dark tresses pinned up into a chic updo, with a few strands left to frame her face.

Meanwhile Kylie looked like a busty bombshell for the night in a low-cut black latex dress that showed off her killer cleavage.

Stassie shared another eye-popping post last Tuesday, where she rocked a green Chrome Hearts bikini on Instagram.

The beauty completed her outfit with a pair of Chrome Hearts jeans which she left unzipped.

Stassie and Kylie have been friends since childhood, after meeting in middle school.

In 2022 Stassie denied having butt implants but hinted that she may have ‘moved some things around’ to alter her derriere

‘She’s definitely my oldest friend,’ Jenner said of Karanikolaou on the season 3 finale of The Kardashians.

In the season 3 finale of The Kardashians on Hulu, they denied they were in a romantic relationship.

‘Isn’t it so funny that everyone thinks that we’re dating these days?’ Jenner said. ‘When we get a little alcohol in our system, we just like to kiss each other and stuff.’

Both are known for their formidable figures, and both have previously opened up about enhancing their looks with plastic surgery.

In 2022 Stassie denied having butt implants but hinted that she may have ‘moved some things around’ to alter her derriere.

She discussed her plastic surgery on the popular Call Her Daddy podcast in April, saying: ‘I have not had butt implants. The only implants that I have are in my t*****s,’ 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.’

‘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,’ Karanikolaou continued.

‘No one needs to tell anyone anything if they don’t want to.’

She said she’s revised some of the work that she’s had done in the past in an effort to look more natural, including removing most of her lip filler and reducing her bust size.

She explained: ‘Over the past couple years, I’ve made my implants smaller, I’ve tried to make everything smaller because I just like the more natural look and I feel like you get caught up when you’re younger.’

‘You grow up, you change, you learn things, you see things differently,’ she added.
