His ex girlfriend is heading to court, but his new girlfriend is courtside.

When Nick Kyrgios defeated Brandon Nakashima at Wimbledon on Tuesday, he had his ever-glamorous girlfriend Costeen Hatzi to thank. 

“I’ve got an incredible support crew,” he told the press after the match. “My physio is one of my best friends. My best friend is my agent. I’ve got the best girlfriend in the world. I’ve just got so many people around me, they just support me.”

It’s fair to assume Kyrgios, 27, will be in need of support at this time. His ex-girlfriend, Chiara Passari, just accused him of assault and he’s set to face a Canberra court on August 2 (read all about that here).

But who is the chic, 22-year-old influencer cum model sitting in the stand at Wimbledon, praising the controversial player’s every move?

The pair have been dating since December last year and Kyrgios is rumoured to have her name tattooed on his body. 

While Hatzi holds a degree in psychological science, she instead pursued a career in interior design, founding her business Casa Amor Interiors just last year. Her designs are where “minimalism meets elegance”. 

Ah, yes. Minimalism.

Kyrgios is known to have showered Hatzi with luxury handbags, expensive gifts and taken her on private planes. She is five years his junior, and has almost 90k followers on Instagram. 

The engagement rumours

Kyrgios appeared to confirm his engagement to Hatzi in March, when he posted an Instagram story using the ring emoji. 

"My babe," he wrote. "We had a great week. We move forward together." 

Further, the pair posted a photo where she appeared wearing a ring.

However, the engagement rumours have not been confirmed, despite Kyrgios teasing the public with claims he would be married "very soon."

Earlier this year he told The Daily Telegraph of his relationship: “Relationships are easy when both people are invested.

“It’s hard to move a couch on your own. I have had a couple past relationships that are brutal when you’re away from them for so long.

"It does affect you when you’re on the court. The luxury I have now in my career is that I’m able to provide for the person and if they want to travel with me they can."
