Nick Kyrgios lashes out at fan who flirted with his girlfriend Costeen Hatzi

Tennis bad boy Nick Kyrgios wants the world to know his girlfriend of a year, Costeen Hatzi, only has eyes for him.

The former world number 13 posted a scathing comment on Instagram after one of Hatzi’s male followers tried to flirt with her.

The 22-year-old influencer, who has 174,000 followers, shared a photo of herself in a tan corset that drew attention to her cleavage.

One fan liked what he saw and cheekily said, “Let’s date?”

But 28-year-old Kyrgios was not in the mood and put the follower in place to remind them that Hatzi was off the market.

“Her dating phase is over,” he wrote, adding a crossed arms emoji.

Hatzi has been dating Kyrgios for just over a year now and regularly accompanies him on his sports tours to cheer him on from the stands.

In April, the WAG and influencer spoke about their romance on The Morning Show.

She revealed that she was a bit ‘skeptical’ of the athlete at first, having heard about his ‘reputation on the field’ through the media, but said she was pleasantly surprised when they first met.

Hatzi, who is now a Bondi Sands ambassador, was also asked about their wedding plans after Kyrgios said she was ‘The One’ during a recent Instagram Q&A.

The couple became Instagram official in December 2021.

Last February, Kyrgios called his girlfriend “The One” and praised her for “bringing out the best in him” in a series of heartfelt posts leading up to Valentine’s Day.

When asked by a follower if he knew she was the perfect match when he first saw her, Kyrgios simply replied “Yes” with a closing emoji.
