His tennis career has been nothing short of turbulent, but Nick Kyrgios’ continues to push forward—and now, he’s got the ultimate supporter by his side. 

The Australian tennis player went public with his girlfriend, Costeen Hatzi in December 2021 after sharing a picture of them both on his Instagram account: “I’m blessed,” he wrote, adding, “This is to the New year & a chance for all of us to get it right.” 

Hatzi also shared some thoughts about her new boyfriend on her own Instagram, which has garnered thousands of followers after Kyrgios’ original post. 

“Not a bad way to start 2022,” she wrote in early January of that year, alongside a picture of the couple posing in front of a mirror.

Costeen Hatzi, whom Kyrgios affectionately calls “Cos” is a 23-year-old blogger based in Sydney. 

She has her own business, Casa Amor Interiors, which sells minimalist, on-trend interior decorations. 

Kyrgios and Hatzi have been vocal about their relationship, posting plenty of updates together since they first went Instagram official. 

“I got ur back like u got mine,” Kyrgios shared in January alongside a picture of the pair embracing. 

Hatzi also travelled to Melbourne with Kyrgios as he competed at the Australian Open in January, and she was spotted court side supporting him during training sessions and games.

How did Nick Kyrgios and Costeen Hatzi Meet?

According to People, the pair met by chance in late 2021 when Hatzi was selling a mirror via Instagram.

Kyrgios reached out while looking for one to purchase, and the rest, as they say, is history.

Who has Nick Kyrgios dated in the past? 

Kyrgios previously dated another Australian tennis player, Alja Tomljanovic, and when they split, he had a brief romance with Russian player Anna Kalinskaya.

He then began dating Chiara Passari in mid-2020—they were together for just over a year before they split for good in October 2021. 

Now, it seems he’s found his game, set and match with Hatzi—perhaps she’ll be the lucky charm he needs for a winning streak…
