Kylie Jenner’s BFF Anastasia ‘Stassie’ Karanikolaou celebrates her sister’s engagement in Cabo

Kylie Jenner’s best friend, Anastasia ‘Stassie’ Karanikolaou, had a lot to be thankful for as she celebrated Thanksgiving and her sister’s engagement on Thursday.

The stunning Instagram model, 25, took to her social media over the holidays to share snaps from Cabo, Mexico, where her lookalike older sister Alexia got engaged in a romantic beach proposal.

“Ahhhh my sister is engaged!!!! i have a brother,” the beauty wrote in the caption, adding, “so much to be thankful for today!!!! i love you all thank you.’

Stassie slipped off her hourglass curves for the occasion in a deep long red silk dress, which she paired with a gold necklace.

The star – who Kim Kardashian’s ex-husband Kanye West admitted to having a crush on – wore her dark brown locks parted in the middle and styled straight.

She accentuated her natural beauty with a touch of blush and pink lipstick and had her nails painted red to match her dress.

Meanwhile, Alexia sparkled in a form-fitting white Fendi dress, her brown curls falling over her shoulders.

Stassie also shared snaps of the moment when the handsome tattoo artist got down on one knee and proposed to the successful hairstylist, who covered her mouth in surprise.

The star was then seen celebrating the special moment with her sister, as they raised glasses of champagne and laughed about it together.

In another flash, the social media phenomenon was seen taking a selfie with her sister and his future brother-in-law.

Also present at the engagement party was Stassie and Alexia’s Greek father, Periklis Karanikolaou, who looked emotional as he hugged his daughter, later sharing a hug with her fiancé.

Another photo showed a family member wiping away Alexia’s happy tears as Stassie looked on proudly.

The beautiful photos continued, with another shot showing the model hugging her sister’s lover while Alexia shared a sweet hug with her dad.

Alexia proudly showed off the giant diamond sparkler on her ring bell in another snap.

Later, the tight-knit group shared a sunset Thanksgiving dinner on the beach to celebrate the proposal.

Though they were childhood friends since they were 10, Stassie became the founder of Kylie Cosmetics, 25, ride or die after her feud with former best friend Jordyn Woods, 25.

Their relationship broke down after news broke that basketball player Tristan Thompson, 31 — Jenner’s older half-brother Khloe Kardashian’s, 38, baby daddy — kissed Jordyn at a party.

Earlier this year, Kylie teamed up with Stassie on a Stassie X Kylie collection with famed Kylie Cosmetics.

During an interview with Peoplethe media star opened up about her longtime friendship with the TV personality.

‘We know too much about each other. We’re stuck together forever,” she said.

She further explained that her mother had dealt with addiction during her childhood, stating that her friendships are monumental in her life. My friends have always been my rock. My friends are my family I could choose.”
