Barely a few months ago, they were nicknamed one of the most emblematic couples of Australian tennis.
Hatzi came from someone who did not know sport to a committed supporter, frequently seen in the field.
In Docuseries Break Point de Netflix, she admitted: “I have never really watched a tennis game in my life, so yes, it’s brand new for me.
Despite his lack of knowledge in tennis, Hatzi adopted the lifestyle and was often credited with having a positive influence on Kyrgios.

“(Costeen) raises him and gives him motivation and inspiration, and she is just a great partner for him.

“And then I go to his practice and there are so many cameras … And I say to myself:” Oh, you are actually a very good tennis player too. “”
While the pair shared many light moments, including a cheeky viral clip in which Hatzi jokingly called a WAG comrade a “b ** ch” during a fashion brand interview, there were signs of mounting pressure.
Hatzi previously shared that she was taking care of all the cleaning tasks at home. “Nick does not have to worry about it,” she said.
Although fiercely competitive, she recognized that no one corresponded to the level of intensity of Kyrgios.
“I don’t think anyone is as competitive as Nick,” she said in January.

The split occurs while Kyrgios tries to return to a higher shape after a long launch of injury.
At the Miami Open, he won his first tour of the Tour since 2022, beating Mackenzie McDonald.
However, his race was interrupted by Karen Khachanov, who dominated in two sets.
Kyrgios’ frustration boiled during the match, leading to a warning from the referee after breaking a bullet in the stands.
