Nick Kyrgios is of course known for his performances on the court, having risen to fame through his exploits as a tennis player.

However, the Australian has also proven to be a “lover boy” and his romance with Costeen Hatzi is currently public knowledge.

The pair have been dating for close to a year now and are even engaged. In a recent love letter shared on Instagram, Kyrgios said he cherishes every moment he shares with Hatzi.

“What a journey we have been on already. My life has honestly never been the same since I’ve met you, you continue to make me smile and be everything I need in tough moments,” he wrote.

“There will always be struggle in life & and I only ever want to ride the ups and downs with you.

“We explore the world and continue to experience all the craziness out there, but this is just a small reminder that I love you & you are my best friend.”

Now let’s look at who Hatzi is in detail.

Who is Nick Kyrgios’ girlfriend Costeen Hatzi?

Costeen Hatzi is also Australian and was raised in Brisbane, Queensland. The 21-year-old had her college education at the Australian Catholic University, where she obtained a degree in Psychological Science.

She works as a model, blogger and social media influencer, and is also into interior products. Hatzi was recently named in Maxim magazine’s Hot 100 Australia list.

In congratulating his girlfriend for the achievement, Kyrgios said: “Congrats Costeen Hatzi, keep working. This is epic, top 21 most influential females in Australia.”

The couple have been going out for over a year now but their relationship was made public last December after Kyrgios separated from his ex-girlfriend Chiara Passari.

Meanwhile, the tennis star has Hatzi’s name tattooed on his leg and believes his girlfriend helps him perform when she watches his games.
