Who is Nick Kyrgios' girlfriend Costeen Hatzi? Relationship explored amid cryptic social media posts

Nick Kyrgios' girlfriend, Costeen Hatzi, is a social media influencer and business owner. Hatzi has worked with several international brands, including YSL Beauty, Ralph Lauren, and more.

The couple have sparked breakup rumors after the Australian tennis star and his girlfriend shared cryptic messages on their social media platforms, Instagram and TikTok.

The two had each other's initials on their Instagram bio, which has now been removed. Hatzi and her friend Golda Monsour posted a video on TikTok with the caption,

"You don't see your friend in a while and you have to update her on your chaotic life."

In the clip, Hatzi can be seen mouthing the words,

"Part 37. Who the f*** did I marry? So at this point in time, I have filed for divorce."

Hatzi was mouthing words from an audio of Reesa Teesa's viral TikTok video, which was a 52-part series about her messy relationship and marriage.

Costeen Hatzi also shared a carousel of photos on March 31, where she can be seen looking at the mirror and applying lipstick, with the caption, "Touch ups." Kyrgios commented on the picture with a simple heart-eye emoji.

The couple has been together since 2021, after they met during an interaction in the same year.
