Nick Kyrgios has thrown the rumour mill relating to his relationship with his girlfriend Costeen Hatzi into overdrive after some speculation had emerged that the pair had split up. 

The rumours arose after they had both removed each other’s initials from their Instagram bios, while Hatzi had also shared multiple cryptic social media posts.

Hatzi, a social media influencer, appeared to publish a post on TikTok which was captioned: ‘You don’t see your friend in a while and you have to update her on your chaotic life’.

The phrase had been made famous by another internet star, Reesa Teesa, who had gained fame for publishing videos regarding her divorce.

One follower responded to the video asking: ‘Do you have a broken heart?’

Rumours had swirled that he and Hatzi had broken up. Hatzi, meanwhile, published a picture of herself doing her make up on Instagram on Monday 

She had captioned the post: ‘Touch ups’ while Kyrgios had commented on the Instagram with a ‘heart-eye’ emoji 

Hatzi replied: ‘No’.

Kyrgios, meanwhile, has published multiple snaps on his Instagram story in recent days, including a picture of a luxury sports car with the caption: ‘Fact of the day… don’t believe everything you read. Stay in your lane.’ He also posted a snap of himself playing with a sausage dog, writing ‘blessed’.

But on Monday, Hatzi published two pictures of herself doing her makeup on Instagram doing her make up.

‘Touch ups,’ she captioned the piece with a ‘dove’ emoji.

Kyrgios responded to the post with a ‘heart-eyes’ emoji, which has ignited more speculation about their relationship on social media.

‘He was apparently scrolling through Insta and saw my business account post,’ she had said.

‘He messaged my business account asking if the mirror was available for pick-up and then messaged my personal [account] asking the same thing.

‘It was a professional/friendly conversation and then he came to pick up the mirror from Sydney.’

In recent days, Hatzi had posted a staged video to TikTok saying she was ‘divorced’ by mouthing the words to a popular internet catchphrase

Hatzi also responded to this question from a follower, but did not respond to questions asking directly if they had broken up

Kyrgios and Hatzi have been an item for almost four years and have posted numerous happy snaps, most of which have been scrubbed from social media now

Hatzi and Kyrgios are understood to have begun dating back in 2021 and were head-over-heels for each other following their first meeting.

The pair had initially met on the social media platform because Hatzi was selling a mirror online.

‘I had no idea this was all a plan, I literally thought he was buying a mirror. He picked up the mirror and, as he would say: “It was love at first sight,”‘ she added.

The pair would later become official in January 2022 and subsequently moved in together in Sydney.

In the past, Hatzi has been Kyrgios’ No 1 supporter, with the social media influencer regularly being seen cheering on the Aussie tennis sensation while he competes on the ATP Tour.

Kyrgios has endured a difficult few years battling back from undergoing surgery on a serious wrist injury that saw him miss nearly all of the 2024 tennis season.

The 29-year-old has since returned to the court but has continued to battle against injuries, notably being hampered by an abdomen strain at the Australian Open, before struggling with his wrist in recent months – notably withdrawing from his clash against Botic van de Zandschulp at Indian Wells.

In Miami, Kyrgios claimed his first ATP Tour singles victory since he underwent surgery on his wrist, beating Mackenzie McDonald at the Miami Open. He would later be knocked out in the second round by Karen Khachanov.

Hatzi, meanwhile, has this year been spotted supporting her beau from the sidelines of the court during his practice sessions this season.
