Nick Kyrgios love life: From Jannik Sinner's ex-girlfriend Anna Kalinskaya to Costeen Hatzi, inside the relationships of the tennis star

Nick Kyrgios has never done anything quietly. From the volleys he hits to the opinions he shares, everything about the Australian tennis star comes with volume. On the court, he has produced some of the most exciting shots the sport has witnessed in recent years. Off it, he has been just as interesting and just as unpredictable. A Wimbledon finalist in 2022 and a former top-20 player, Kyrgios has spent the better part of a decade as one of tennis's most talked-about personalities and that conversation has never been limited to what happens between the lines.His personal life has always drawn attention, partly because Kyrgios has never been particularly guarded about it. His candid social media presence and outspoken nature have meant that his relationships often play out at least partially in public view. Here is a look at the relationships that have shaped his story off the court.Nick Kyrgios' first well-known relationship was with fellow Australian tennis player Ajla Tomljanović. The two dated between 2015 and 2017. It was the kind of pairing that made natural sense. Two young Australians navigating the same world at the same time. They even partnered up for mixed doubles at the 2016 Australian Open, which gave fans a rare glimpse of them on the same side of the net. When they eventually went their separate ways, both continued building careers that would take them to very different places in the sport.After his relationship with Tomljanović ended, Kyrgios was linked to Russian tennis player Anna Kalinskaya, who later went out with Jannik Sinner. More publicly, he went on to date Australian influencer Chiara Passari from around 2020 to 2021. The relationship attracted a lot of attention and not always for the right reasons. Their breakup sparked a wave of headlines and legal proceedings that kept both names in the news long after the relationship itself had ended. The most significant relationship of Kyrgios' life so far began in one of the more unlikely ways you will come across. In late 2021, he came across Australian social media influencer Costeen Hatzi's Instagram page, where she had listed a mirror for sale. He sent her a message. That was how it started.What followed quickly became one of the most talked-about relationships in Australian tennis. Hatzi became a regular presence at his matches and was in the stands for some of the biggest moments of his career, including his remarkable run to the Wimbledon final in 2022. Their relationship also featured in the Netflix tennis series Break Point, which gave fans a genuinely personal look at Kyrgios away from the noise and the controversies. In 2025, Nick broke silence on their breakup and said he wished her well. He is now rumored to be dating Melbourne-based marketing manager Alexia Alessi.
