Nick Kyrgios joined girlfriend Costeen Hatzi at Hello Molly's exclusive 10th anniversary boat party in Sydney on Thursday.
In addition to Tammy Hembrow, Skye Wheatley, and Kylie Jenner's best friend Greek American Anastasia Karanikolaou, the upscale event was also attended by the 27-year-old tennis champion.
The loved up looked thrilled to attend the exclusive VIP event alongside new Bachelorette runner-up Bella Varelis and former reality star Amelia Marni.
Her appearance comes as rumors swirl Nick and Costeen are about to announce their engagement.
The pair confirmed their romance last year and Costeen has since become his number one fan box, cheering him on at Wimbledon and the US Open.
It’s been a productive professional year for Nick and he’s likely to start 2023 in the world top 20 and be seeded at next January’s Australian Open.
