Greek-Australian tennis icon Nick Kyrgios and influencer Costeen Hatzi have reportedly parted ways after nearly four years together. Known for his fiery talent and proud Hellenic roots, Kyrgios has been a beloved figure both on and off the court. The couple, once dubbed one of Australian tennis’ most iconic duos, built a life filled with love, travel, and a dachshund named Boo—yet lifestyle differences have led them to new paths. As Kyrgios stages an inspiring comeback in the US, his Greek spirit continues to shine bright.
