Nick Kyrgios Moves On: Clues Suggest Split from Influencer Girlfriend Costeen Hatzi

Nick Kyrgios and Partner Costeen Hatzi Split After Three Years Amid Lifestyle Differences

Australian tennis star Nick Kyrgios and influencer Costeen Hatzi have reportedly ended their relationship after more than three years together. The split, fueled by growing lifestyle differences, marks the end of one of Australian sports’ most high-profile romances.

Signs of Trouble

Insiders cited Kyrgios’ “party boy” persona as a key factor. “She would have to accept how he rolls, and she won’t anymore,” a source told The Daily Telegraph. The couple recently removed each other’s initials from their Instagram bios, while Hatzi, 24, has returned to Australia from the U.S., where she had been supporting Kyrgios during his tennis comeback.

From Instagram DM to Power Couple

The pair met in late 2021 when Kyrgios messaged Hatzi about a mirror she was selling. Their connection blossomed quickly, with Hatzi calling it “love at first sight.” They went public in early 2022 and moved into a Sydney apartment months later. Despite her lack of tennis knowledge, Hatzi became a fixture on the tour, accompanying Kyrgios globally.

Support Through Struggles

Hatzi stood by Kyrgios during his injury battles, including surgeries that sidelined him from the 2025 Australian Open. The couple adopted a dachshund, Boo, with Hatzi calling them “my family” on social media. Kyrgios’ manager praised her positive influence, noting she “lifts him up” compared to past relationships.

Cracks in the Facade

Despite public affection, behind-the-scenes tensions emerged. Hatzi handled household duties, quipping, “Nick doesn’t have to worry about that,” but sources suggest their clashing lifestyles took a toll. While Hatzi embraced her role as a “WAG,” she balanced it with influencer work for brands like Bondi Sands.

What’s Next?

The split coincides with Kyrgios’ attempted return to form. At the Miami Open, he secured his first tour win since 2022 but fell to Karen Khachanov afterward, showcasing lingering frustration. Meanwhile, Hatzi focuses on her career in Australia.

Both parties have yet to comment publicly, leaving fans speculating about the future of tennis’ former “it” couple.
