One of Kylie Jenner's closest friends, Anastasia Karanikolaou, might have just recently crossed the line with her former boyfriend Tyga.

In what appears to be a major violation of girl code, Karanikolaou may have been spending time with Tyga -- and showcasing their potential interaction with a photo shared on social media.

On April 3, Hollywood Life shared a photo of what appears to be Karanikolaou posing beside an orange Bugatti while wearing a jean outfit and black crop top. However, as the outlet pointed out, it's hard to say for absolute certain that the woman in the photo was, in fact, Karanikolaou.

Tea Tenders on Instagram posted the image on their page, along with a photo that showed Tyga in the same location with the same Bugatti. Also seen in the second photo of the rapper was a white convertible, which was not seen in the photo of Karanikolaou.

Kylie Wasted No Time Moving On From Tyga

By most accounts, Tyga seemed to be Jenner's first love. So, when they broke up at the beginning of last year, many believed they would get back together as they had in the past. However, that didn't happen, and within weeks of their split, Jenner was already dating Travis Scott.

Jenner not only moved on from her romance with Tyga quickly, she also got pregnant with Scott's baby just weeks later. Then, in early February, her daughter Stormi Webster arrived. Since then, Jenner and Scott have been keeping a low profile as they continue to adjust to their new roles as mom and dad.

Tyga Misses Kylie 

According to an insider, Tyga has been dealing with major regrets since the year he and Jenner called it quits and has been further hurt by the fact that he was once close to her new baby daddy, Scott.

“Tyga is heartbroken after seeing Stormi’s cute baby pics online. Tyga has been trying to work hard, move on and put the past behind him but he still misses Kylie a lot. Stormi is a big reminder to Tyga what could have been with him and Kylie if he had been a better boyfriend,” a source close to the rapper told Hollywood Life.

Keeping Up With the Kardashians is expected to return to the E! Network later this year for Season 15.
