Australian tennis stars Nick Kyrgios and Thanasi Kokkinakis are making the most of their free time ahead of attending the 2023 Wimbledon tennis championships.

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

The four appeared relaxed as they made their way through the crowd, occasionally breaking up in twos for separate chats.

He dressed simply for the occasion, sporting a gray hoodie, black pants and a backpack.

Speaking to the Herald Sun in the evening, Hannah said she and Thanasi met “a few months ago” and that she had been traveling with him “for a while”.

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

‘[I’m a] I guess you could say a late bloomer, so I’m trying that, but that comes with its challenges. But she was great,” he said.
