“I can’t thank you enough for everything you have taught me.

“You are one in a million and I’m so lucky I get to spend every day with you.

“I love you beyond words & love all the memories we have created together.

“To many more birthdays, Enjoy your special day.”

Kyrgios wrote beneath Hatzi’s heartfelt post: “Thanks beautiful”, adding love heart and kissing emojis.

In one photo, the couple look glammed up as they posed in a vineyard at the recent wedding of Kyrgios’ brother Christos.

In others, they hug on court and at after-match press interviews.

In more private moments, the couple is shown dancing at home and wearing Oodies in the kitchen.

Hatzi’s followers loved her words – and the sweet photographs.

“Love you guys together,” one person wrote.

“The best couples build each other up to be the best versions of themselves!” wrote another.

“Happy birthday Nick.”

Many fans adored the throwback photo of a young Nick.

“I just love that little guy’s face,” one follower said.

“He grew up handsome, but that little guy melts my heart.”

“Cutest couple on tour,” enthused another.

“Gorgeous couple who seems to bring out the best in each other,” noted another.

A couple for 18 months, the pair now lives together and travels the world for Kyrgios’ tennis commitments.

Hatzi recently appeared on The Morning Show to address persistent rumours about impending nuptials.

When co-host Larry Emdur asked if they’d already picked out “the ring”, Hatzi demurred.

“No, no, no, none of that yet,” she said.

“If it happens, it happens, if it doesn’t, it doesn’t, I’m just going with the flow.

“We’re happy and healthy and, yep, that’s all that matters.”
