Anastasia Karanikolaou shares photo dump with unique t-shirt
Anastasia Karanikolaou, known as Stassie, shared a photo dump on Instagram on August 28, 2025, captioned, “camera roll clean out.”
The upload included a series of images from different settings, such as makeup-free selfies, a skincare treatment, casual home moments with her cat, and pictures taken while out with friends. One image stood out, showing her wearing a fitted white T-shirt with the printed phrase, “my mental health isn’t great but my t**s are.”
Karanikolaou has been in the Kardashian-Jenner circle for more than a decade, maintaining a close friendship with Kylie Jenner since middle school. Jenner described her on The Kardashians as “definitely my oldest friend,” noting, “we grew up together, we’ve been through so much together. She’s like a sister” (via People). The pair first met at a Barnes & Noble in Calabasas and have remained inseparable, often addressing public speculation about their bond.
Beyond her social media presence, Karanikolaou has built a career as both a model and an entrepreneur. She co-founded Sunny vodka with Zack Bia in 2022. Later that year, she promoted the brand in Las Vegas. She has also collaborated with Kylie Jenner on a Kylie Cosmetics collection. In addition, she has modeled for Savage x Fenty, Pretty Little Thing, and Alexander Wang.
Karanikolaou has been open about her cosmetic procedures. She has had lip fillers, a breast lift in 2017, and a breast implant reduction in 2019. She documented parts of this journey on YouTube, where she has more than 750,000 subscribers. Alongside her channel, she has grown her Instagram following to nearly 11 million. She was long known under the username “stassiebaby.”
Her personal life has also been in the spotlight. She dated TikToker Jaden Hossler before confirming their split in April 2024. In June 2023, she and her sister, Alexia, announced the death of their mother, writing in a joint Instagram post, “Heaven gained someone so special… We’ll miss you everyday.”
