In a heartfelt and candid revelation, Costeen Hatzi, the former partner of Australian tennis star Nick Kyrgios, has opened up about a significant personal transformation, sharing details of her shocking weight loss following what she described as a "really tough chapter" in her life.
The 22-year-old influencer and university student, who was in a high-profile relationship with Kyrgios until their split earlier this year, took to social media to share her journey, posting a series of before-and-after photos that showcased a dramatic physical change and speaking openly about the emotional struggles that preceded it.
The End of a Public Romance
Hatzi's weight loss revelation comes several months after her separation from Nick Kyrgios, a split that captivated tennis and celebrity news outlets. The couple, who had been together since late 2021, were a constant presence in each other's social media feeds and public appearances, with Hatzi often seen supporting Kyrgios during his matches on the global tennis circuit.
Their relationship was documented extensively, from Kyrgios' runner-up finish at the 2022 Wimbledon Championships to his various injury struggles. Hatzi, who was studying a double degree in commerce and law while managing her influencer career, became a familiar face to tennis fans, often seen in the player's box during Kyrgios' most significant matches.
The breakup, confirmed in early 2024, was described by sources close to the pair as amicable but undoubtedly challenging. In her recent social media posts, Hatzi alluded to this period without going into specific details, stating simply that she had endured "a really tough chapter that I kept very private."
A Transformative Journey
The physical transformation that Hatzi revealed to her followers was striking. Sharing side-by-side photographs, she displayed a noticeable weight loss, explaining that the change came after she decided to focus intensely on her health and wellbeing following personal difficulties.
In her caption, she wrote: "I went through a really tough chapter that I kept very private and decided to completely turn my life around and focus on my health. I lost 12kg and completely transformed my lifestyle, my mindset and my happiness."
The 12-kilogram (approximately 26-pound) weight loss represents a significant physical change for the influencer, who has historically maintained a curvier figure throughout her public relationship with Kyrgios. Followers and fans were quick to comment on the transformation, offering both support and admiration for her honesty.
The Pillars of Her Transformation
Hatzi didn't just share the results of her weight loss; she provided insight into the methods behind her transformation, emphasizing that it was about more than just physical change. She highlighted several key areas she focused on during this period of personal growth:
- Consistent Exercise Routine: Implementing a regular fitness regimen
- Nutritional Changes: Completely overhauling her diet and eating habits
- Mental Health Focus: Prioritizing psychological wellbeing alongside physical health
- Lifestyle Shift: Making permanent changes to her daily routines
- Mindset Work: Developing a more positive outlook on life
This comprehensive approach suggests that Hatzi's transformation extended far beyond superficial weight loss, touching on deeper aspects of personal development and self-care during a challenging transitional period in her young life.
Life After a High-Profile Split
The end of Hatzi's relationship with Kyrgios marked a significant shift in her public identity. During their time together, she had become intrinsically linked with the controversial tennis star, often appearing in his YouTube vlogs and social media content, and becoming a subject of media attention in her own right.
Since their separation, both individuals have pursued different paths. Kyrgios has continued to grapple with persistent injuries that have limited his tournament participation, while also expanding his media presence through commentary roles and continued content creation.
Hatzi, meanwhile, has refocused on her studies and personal brand, completing her university degrees and reestablishing her independent identity separate from the tennis world. Her decision to share her weight loss journey appears to be part of this broader effort to redefine herself publicly and personally.
The Response and Moving Forward
The reaction to Hatzi's revelation has been overwhelmingly positive, with followers praising her vulnerability and dedication to self-improvement. Many commenters noted the visible change in her confidence and demeanor, not just her physical appearance, suggesting that the transformation she described was indeed comprehensive.
One particularly poignant aspect of her message was the emphasis on happiness as an outcome of her journey. Rather than focusing solely on the weight loss itself, she framed it as part of a larger pursuit of contentment and wellbeing, writing that she had transformed "my lifestyle, my mindset and my happiness."
This perspective resonates with increasing public awareness about the connection between mental health and physical transformation, particularly when significant life changes like the end of a relationship create both challenges and opportunities for personal growth.
A New Chapter Begins
As Costeen Hatzi moves forward from what she openly acknowledges was a difficult period, her story serves as a powerful reminder of the resilience possible in the face of personal challenges. Her decision to share this journey publicly, while maintaining boundaries around the specific details of her struggles, demonstrates a nuanced approach to life in the public eye.
The transformation—both physical and mental—that Hatzi has undergone since her split from Kyrgios speaks to the universal human capacity for renewal and self-reinvention during times of transition. While the specific circumstances of her "really tough chapter" remain private, the outcome is visibly and inspirationally public.
As she continues to build her life post-relationship, focusing on her education, career, and personal wellbeing, Hatzi's journey offers insight into the ways personal challenges can become catalysts for positive change, and how difficult endings can sometimes create space for beautiful new beginnings.
