She may best be known as  Kylie Jenner’s BFF.

But Anastasia ‘Stᴀssie’ Karanikolaou is shining all on her own.

The 23-year-old model brightened up her 8.4million followers’ Instagram feeds on Monday as she shared a very sultry snap of herself in a yellow thong ʙικιɴι.

Her newly-dyed brunette tresses were worn down as they cascaded down the side of her face which had complementary make-up on it including dark red lip.

No doubt it has been a fun summer for Stᴀssie as she celebrated her 23rd birthday bash with BFF Kylie last Monday.

In the the pH๏τo shared with Stᴀssie’s followers the 22-year-old Kylie Cosmetics CEO ignored social-distancing rules as she fearlessly cozied up to her crew.

DailyMail.com reached out to Kylie’s representative for comment.

Kylie, Stᴀssie, and the rest of the party attendees wore matching black sweatsuits with ‘Stᴀssie Turns 23’ printed across the front in red and white lettering which was a reference to basketball great Michael Jordan who wore that number.

Kylie rocked her signature brown eyeshadow and winged liner look, which she paired with a flattering neutral ɴuᴅᴇ lip.

Her shoulder length tresses were neatly parted down the middle and meticulously straightened in order to draw attention to her trendy blonde streaks.

‘missing liv and taylor but these are my humans.. i appreciate you all more than you know ❤️ thank you for a special night,’ captioned Stᴀssie on the group pH๏τo.
