Tennis star Nick Kyrgios and girlfriend Costeen Hatzi’s relationship reportedly over

Australian tennis ace Nick Kyrgios and girlfriend Costeen Hatzi have reportedly ended their four-year relationship.

The rumours have come after observers started noticing recent cracks in their relationship.

The power couple first started dating in 2021 and since then the 24-year-old Hatzi has become a social media influencer (with over 180,000 followers on Instagram) and a high-profile figure on the tennis tour.

Kyrgios has regularly spoken about his love for Hatzi and, in 2023 when the couple acquired a pet dog, Kyrgios said, “My beautiful family.”

He has also previously called Hatzi his “closest friend, the person who hates me one minute and loves me the next, the best girlfriend, my biggest fan, my love, and a great partner in life”.

However, it now seems that the relationship has come to a “sour” end.

In a telling detail, the couple have both removed each other’s initials from their Instagram bios.

And it has also been reported that Hatzi flew out of the US and headed home.

She reportedly made that decision after “the relationship soured”.

In 2022, Kyrgios told fans on social media that he thought Hatzi was the one.

And Hatzi also addressed engagement talk on Channel 7’s The Morning Show in 2023

“I mean, if it happens, it happens, if it doesn’t, it doesn’t,” she said.

“I’m just going with the flow and we’re happy and healthy and, yeah, that’s all that matters.”

After they had been together for around two years, Hatzi shared a carousel of images of their time together.

“I can’t thank you enough for everything you have taught me,” she said to Kyrgios.

“You are one in a million and I’m so lucky I get to spend every day with you.

“I love you beyond words & love all the memories we have created together.”

It has been reported that Hatzi has had enough of Kyrgios and his “party boy” ways.

In 2023 Kyrgios addressed those habits, saying all the “drinking and partying” would certainly mean he’s career would be over by the time he turns 33.

“There’s no chance I’m playing until 33. Kyrgios playing until 33 is insane .... I promise you, when I’m gone, you’ll never see me again,” he said.

“The schedule is out of control (and) I’m getting old ... 28, yeah. But all the drinking and partying, I’m like 57.”
