Kylie Jenner's bestie Anastasia Karanikolaou turns up the heat with her bewitching photoshoots

Anastasia Karanikolaou also goes by the name Stassie or Stassie Baby on social media. Her father Periklis Nikolaos Karanikolaou is a Greek-born broker for World Financial Group. Stassie is Kylie Jenner's best friend; she poses with her in matching outfits and liking all her pictures on Instagram. She also has a matching tattoo that read 'Stormi'—the name of Jenner's child. Stassie is the youngest self-made billionaire for nine years, according to Forbes' list. Stassie is also a famous social media influencer and plastic surgery fan, speaking openly about her procedures on social media. She has over 200,000 YouTube followers and over ten million Instagram followers. Stassie poses in different outfits for her followers and occasionally vlogs about her life. One of her vlogs was about her entire plastic surgery journey. Dr Ashkan Ghavami, a celebrity plastic surgeon, who is also the man behind Iggy Azalea's breast and nose procedures, did her surgery. However, one of Stassie's breasts was nearly a full cup size up than the other one that made it difficult to find bras which fit. Stassie has also worked with brands including PrettyLittleThing and Good American on limited fashion collaborations and campaigns. (All photos: Instagram)
