Costeen Hatzi reveals whether boyfriend Nick Kyrgios will continue playing tennis after crashing out of Australian Open

Costeen Hatzi has shed light on her tennis champion boyfriend's future in the sport after she crashed out of the Australian open earlier this week.  

Hatzi, who is the loyal girlfriend of player Nick Kyrgios, says that she is encouraging the champion to return for a future bout at the Australian Open. 

'The fact that he was back on the court at the AO after so many injuries, surgeries, I'm really proud of him' she told the Daily Telegraph on Friday. 

'I can't say for sure (it was his last), it just really depends on how he's feeling, how his body holds up because he can't keep putting his body through so much pain.

'But don't worry I will be encouraging him to keep going.'

Costeen added that in terms of Nick's future in tennis, he's 'not stopping until he's 40 years old like (Novak) Djokovic'.

The confession comes after Nick admitted on Tuesday evening that this could be the last time he would play singles at the Australian Open. 

The injury-plagued star said he had battled hard not to throw in the towel during his three-set defeat by British star Jacob Fearnley as his abdominal strain took its toll during the match. 

Doubts had been raised over his fitness coming into the Australian Open, with the 29-year-old, who has battled hard to come from a career-threatening wrist injury, previously admitting that it would be a 'miracle' if he could make it back for the first slam of 2025. 

But after being knocked out of his home slam, Kyrgios raised fears over his future playing career: 'Realistically, I can't really see myself playing singles again here. 

'So... It was special. I've taken that in. It was pretty good. I mean, yeah, I knew I had doubles and I was kind of taking everything in tonight, in those moments.'

'It was nuts. But yeah, I didn't want to just throw in the towel or walk off or retire.' 

He added that he was 'hurting physically' but he wasn't going to let down the fans 'who had waited hours' outside Melbourne Park to get into the grounds. 

The Aussie had shared snaps of the huge queues of fans waiting outside the tournament to get into the stadium on his Instagram, with some stating that they had been in line for nearly five hours. 

But after taking a big sigh, again the Australian, who had previously said that tennis had been 'mundane' without him repeated himself: 'Again, I can't see myself realistically playing a singles match here again.' 

Kyrgios, tennis' great entertainer, explained his feelings after suffering the 7-6 (7-3) 6-3 defeat by British star Jacob Fearnley with the Australian stating that it was 'hard.' 

On Monday, Costeen led the charge of glamorous WAGs attending the Australian Open Bondi Sands event at the Royal Botanic Gardens. 

The 24-year-old looked casually chic in a fitted white, sporty mini dress with short sleeves that placed her trim pins on display. 

Costeen celebrated her three year anniversary with tennis pro Nick, 29, this month and last Sunday, began hosting Stan's live coverage of the tournament. 

She has undergone quite the style transformation since kicking off her fashion influencer career in 2021. 

Costeen has worked with a wide array of top brands and even walked in her very first runway show at the Hunting Hue launch last October in a major milestone.

Now well-known for her flawless style, she rakes in between four and five figures for each of her sponsored posts.

Now well-known for her flawless style, Hatzi also rakes in between four and five figures for each of her sponsored posts as she makes a living off her wardrobe.

However, it has been quite the journey for Hatzi as she admitted she hasn't always had the same eye for fashion while speaking exclusively to Daily Mail Australia.

Several years ago, she instead could be seen sporting cropped shirts, pleather trousers and neon tones, rather than the elegant evening wear she is now known for.

'Maybe like three years ago when I started seeing Nick, I didn't know what styles worked for me and I got photographed in not the best clothes,' she admitted.

The Sydney-based businesswoman said celebrity fashionistas including Hailey Bieber have heavily influenced her fashion evolution, as well as her regular use of Pinterest.

She shared: 'Hailey Bieber, I love what she wears, she's such a style icon. I feel like every young girl would say Hailey Bieber.'

Hatzi didn't start her career in fashion but was studying and working at a car dealership before meeting Nick, when she launched her career as a full-time influencer. 

She graduated from the Australian Catholic University with a Bachelor of Psychology in May 2021, and now runs her business Style Studio Dress Hire as well as supporting Nick's tennis career.
