The world of tennis is no stranger to drama, but lately, the spotlight has shifted off the court to the personal life of one of its most polarizing stars, Nick Kyrgios. Rumors of a split between the Australian tennis maverick and his long-time partner, influencer Costeen Hatzi, have swirled for weeks, fueled by cryptic social media posts and subtle changes in their online presence. On Tuesday, Hatzi stepped into the public eye at a high-profile event in Sydney, breaking her silence on her recent endeavors and offering a glimpse into her life amid the speculation. While she didn’t directly address the status of her relationship with Kyrgios, her poised demeanor and focus on her career spoke volumes about her priorities in this turbulent moment.
The whispers of a breakup began in late March when fans noticed that Hatzi, 24, had returned to Australia from the United States without Kyrgios, who has been grinding through a comeback after a wrist injury sidelined him for much of the past two years. Adding fuel to the fire, the couple—once inseparable on social media—removed each other’s initials from their Instagram bios, a move that eagle-eyed followers interpreted as a sign of trouble. Hatzi, a Sydney-based influencer with over 180,000 followers, further stirred the pot with a TikTok video where she mouthed the words, “Who the f*** did I marry? So at this point in time, I have filed for divorce.” Though she later clarified it was a joke, the post, captioned “Spilling the tea,” sent the rumor mill into overdrive. Kyrgios, never one to shy away from a response, seemed to downplay the speculation, dropping a heart-eyes emoji on one of Hatzi’s Instagram posts and later writing on his Instagram Story, “Fact of the day… don’t believe everything you read. Stay in your lane.” Yet, the ambiguity left fans hungry for clarity.
At the Witchery White Shirt Campaign launch in Sydney, Hatzi radiated confidence, her focus firmly on her burgeoning career. Dressed impeccably, she mingled with fellow influencers and spoke about her recent collaborations with major brands, a testament to her growing influence in the fashion and lifestyle space. “I’m grateful to have this life and hopefully keep on going,” she said, her words carrying a quiet determination. For Hatzi, who graduated with a degree in psychological sciences from Australian Catholic University in 2021, the influencer world has been a natural fit. She’s carved out a niche with her authentic content, from sharing glimpses of her Sydney apartment to promoting brands like Bondi Sands and Prada Beauty. Her recent posts—showcasing glamorous events, boat parties with friends, and a cocktail-fueled “golden hour” by the waterfront—paint a picture of a woman embracing her independence, regardless of the rumors.
The story of Hatzi and Kyrgios began in 2021 with a serendipitous Instagram exchange over a mirror she was selling. “He messaged my business account asking if the mirror was available for pick-up and then messaged my personal [account] asking the same thing,” Hatzi once recalled, describing their connection as “love at first sight.” By January 2022, they were official, moving in together in Sydney and becoming a fixture on the tennis circuit. Hatzi, who admitted she “never really watched a tennis game” before meeting Kyrgios, became his biggest cheerleader, traveling the globe to support him through triumphs and setbacks. From Wimbledon to the U.S. Open, her presence was a stabilizing force for the often-volatile star, with Kyrgios’ manager Daniel Horsfall noting, “[She] lifts him up and gives him motivation and inspiration.” Kyrgios himself has called her “the best girlfriend” and “my biggest fan,” crediting her support during his grueling recovery from injury.
But whispers of discord have pointed to lifestyle differences as a potential wedge. Insiders have suggested that Kyrgios’ penchant for a fast-paced, party-driven life clashes with Hatzi’s evolving priorities. “Nick is a party boy. He always has been,” one source claimed, while another added, “She would have to be willing to accept how he rolls, and she won’t anymore.” Hatzi’s recent solo outings—dining at Neptune’s Grotto with friend Sarah Maloney, attending luxe influencer events, and raising a glass to the “good life”—hint at a shift toward self-discovery. When asked by a follower if she had a “broken heart,” she replied simply, “No,” a response that suggests resilience, if not resolution.
For now, neither Hatzi nor Kyrgios has confirmed or denied the split, leaving fans to piece together the puzzle. Kyrgios, meanwhile, is focused on his tennis comeback, recently securing his first ATP Tour win since 2022 at the Miami Open. As Hatzi continues to build her brand and Kyrgios battles to reclaim his spot among the elite, their paths seem to diverge—at least for the moment. Yet, their history of weathering storms together keeps hope alive for some that this is just a rough patch. Whatever the truth, Hatzi’s latest chapter is one of empowerment, proving she’s more than just a courtside companion—she’s a force in her own right, ready to shine with or without the tennis star by her side.
