Nick Kyrgios, Thanasi Kokkinakis hit the shops with girlfriends Costeen Hatzi and Hannah Dal Sasso

Australian tennis stars Nick Kyrgios and Thanasi Kokkinakis are making the most of their downtime ahead of competing in the 2023 Wimbledon tennis championships.

The duo were spotted in central London on Tuesday with their respective girlfriends Costeen Hattzi and Hannah Dal Sasso, visiting high-end stores such as Balenciaga, Hermes and Chanel.

The foursome looked relaxed as they navigated the crowd, occasionally breaking into pairs for separate conversations.

Nick, 28, stayed true to his bad boy reputation by throwing the birdie at the onlookers as the foursome left a designer shop.

He dressed smartly for the occasion, wearing a gray hoodie, black pants and a backpack.

Proving himself to be the ultimate Instagram boyfriend, Nick was at one point spotted taking pictures of Costeen, 22, as she posed on the sidewalk.

His influencer girlfriend looked effortlessly chic in a black crop top and maxi dress layered under a striped shirt worn open.

Showing off her expensive taste, the brunette accessorized her look with a black Chanel handbag worth around $10,000.

Costeen’s shopping trip proved successful, as she was holding a large Zara shopping bag towards the end of the outing.

27-year-old Thanasi, who was eliminated in the first round of Wimbledon qualifying, looked sporty in a white T-shirt, black shorts and a blue bucket hat.

He added a preppy touch to his outfit by tying a black sweater over his shoulders.

Talking to the Announce sun that night, Hannah said that she and Thanasi met “a few months ago” and that she traveled with him “for a while.”

In May, Thanasi paid tribute to Hannah after winning his first French Open win, admitting she was his “first girlfriend, probably ever.”

‘[I’m a] late bloomer, you might say, so I try, but that also brings its challenges. But she’s been great,” he said.

Nick is back in London a year after his successful stint at the 2022 Wimbledon tennis championships, where he was beaten runner-up by Novak Djokovic.

He was spotted practicing Wimbledon on Wednesday afternoons with Costeen watching from the sidelines.

Nick only played one game this year after undergoing surgery to address the injury that shut him out Australian Open in January.

The Aussie star sensationally pulled out of the tournament due to a knee injury just a day before he was due to play his first round match against Roman Safiullin.
