Tennis star Nick Kyrgios is gearing up for the start of the 2025 season with the first Grand Slam of the Year, the Australian Open, and his girlfriend Costeen Katzi will be right by his side. Costeen is often sitting courtside in support of her boyfriend, and she made sure to show up to Melbourne in style.

Mats Wilander believes Nick Kyrgios has the capability of causing a 'big upset' in the Australian Open, but has raised concerns about the Aussie star's fitness. Kyrgios' first-round match against Jacob Fearnley next week will be his first match in a major tournament in over two years.

Nick Kyrgios risks having to miss the Australian Open 2025 - which will start on Sunday 12 January - due to a new physical problem. The Australian tennis player has communicated to fans, through an Instagram story, how he is struggling with another type of injury that is quite serious and will have to be monitored in the coming days.
