In a candid moment that has sent shockwaves through the tennis world, Nick Kyrgios has finally addressed the swirling rumors about his breakup with longtime girlfriend Costeen Hatzi, confirming their separation after nearly four years together. The Australian tennis star, known for his fiery on-court persona and off-court charisma, took to Instagram on June 11, 2025, to share his feelings during a fan Q&A, putting an end to months of speculation. “Things happen. I wish her nothing but the best. So many incredible moments that will stay with me,” Kyrgios said, reflecting on the end of a relationship that once seemed destined for a fairy-tale ending. The confirmation marks a poignant chapter for the couple, whose love story captivated fans since it began in December 2021.
The romance between Kyrgios, 30, and Hatzi, 25, started with a serendipitous encounter that could have been scripted for a romantic comedy. Kyrgios, scrolling through Instagram, stumbled upon a post from Hatzi’s home decor business, Casa Amor Interiors, advertising a mirror for sale. What began as a simple inquiry about the mirror turned into a whirlwind romance. “It was love at first sight,” Hatzi once recalled, describing how Kyrgios visited her Sydney home to pick up the item, sparking an instant connection. By January 2022, the couple went public, and Hatzi became a fixture in Kyrgios’s life, cheering him on from the player’s box during his remarkable 2022 season, which included a Wimbledon final and an Australian Open doubles title with Thanasi Kokkinakis. “Meeting Costeen was probably my favorite moment, probably the best thing that’s happened to me,” Kyrgios said that year, crediting her support for his on-court success.
However, cracks began to appear in March 2025, when fans noticed subtle changes on social media. The couple, once prolific in sharing their lives together, unfollowed each other on Instagram and removed each other’s initials from their bios. Hatzi’s cryptic TikTok posts, including one where she mouthed, “Who the f*** did I marry? So at this point in time, I have filed for divorce,” fueled speculation. Her return to Australia alone after supporting Kyrgios at Indian Wells further intensified rumors. In April, Hatzi confirmed the split in an interview, saying, “We haven’t spoken… I hope he finds peace and happiness within himself. I definitely entered the relationship with pure intentions.” She emphasized her focus on personal growth and her career, noting, “I’m still going on with work and I have a few different brands that I’m working with at the moment. I think it’s always important to put yourself first and do what makes you happy.”
Kyrgios initially downplayed the rumors, calling them “fake news” and leaving a heart-eyes emoji on one of Hatzi’s Instagram posts. But his recent comments reveal a reflective acceptance of the breakup. The split coincides with a challenging period for Kyrgios, who has been sidelined by injuries, including a wrist reconstruction that kept him off the ATP Tour for much of 2024. His 2025 comeback included a first-round win at the Miami Open but was marred by a retirement at Indian Wells and a loss to Karen Khachanov in Miami. Off the court, Kyrgios has faced personal struggles, admitting in his Q&A, “I’m always ok. But definitely going through some real stuff at the moment. Injuries, family. But trying to push forward and be better every day.”
Hatzi, a social media influencer with nearly 180,000 Instagram followers, has carved out her own identity through her businesses, Casa Amor Interiors and Style Studio, a dress hire company. Her presence on the tennis circuit was credited with stabilizing Kyrgios, with his manager Daniel Horsfall noting in 2023, “She lifts him up and gives him motivation and inspiration.” Past talks of marriage and starting a family, with Hatzi saying, “It’ll happen when it happens,” now seem like distant memories. Recent reports suggest Kyrgios may be moving on, with flirty Instagram exchanges with Love Island star Mia Dalkos sparking new romance rumors, though his representatives insist they are just “good friends.”
As Kyrgios prepares for a potential return at the French Open, partnering with Jordan Thompson in doubles, and Hatzi focuses on her entrepreneurial ventures, their breakup closes a significant chapter. Fans, while heartbroken, are left with the couple’s shared legacy of love and support, and both stars seem poised to embrace their futures with resilience and grace.
