Nick Kyrgios went Instagram official with his new girlfriend Costeen Hatzi last month.
And it appears the pair's blossoming romance is certainly heating up, as the duo were spotted sharing a smooch together during his practice session for the Australian Open on Sunday.
Nick, 26, and his 21-year-old flame appeared besotted with each other as they sat in the stalls of Melbourne Park, ahead of his first match in the tournament on Tuesday.

Meanwhile, Costeen looked as glamorous as ever in a navy vest top and tiny shorts, which she teamed with a pair of black-and-white sneakers.
