Nick Kyrgios and his girlfriend Chiara Passari climb Sydney Harbour Bridge

Tennis star Nick Kyrgios and his girlfriend Chiara Passari have taken their relationship to a new high.

Nick Kyrgios and his girlfriend Chiara Passari have taken their relationship to a new high — with a romantic walk up Sydney’s Harbour Bridge.

The tennis superstar shared photos on his Instagram story on Sunday asking fans to vote for “Who has the swaggy bridge photo” out of the loved-up pair.

He also posted a photo of the two of them together saying: “This was quite the climb. Harbour Bridge complete.”

Rumours suggested the couple had called it quits on their relationship in early February before Kyrgios had gone to Melbourne for the Australian Open.

Kyrgios appeared to delete all but one image of Passari on his Instagram after she posted a cryptic message about “cheaters” before the Open kicked off.

Passari didn’t mention any names or reference him in her post, which was uploaded to her Instagram story.

“Cheaters always want you to be loyal while they’re being unfaithful,” it read.

Passari added the caption “It keeps getting better y’all”, with several upside down smiling emojis.

But Passari later jetted in to Melbourne for lockdown after Kyrgios’ Australian Open singles exit, suggesting they had mended fences.

Later that month, Passari issued a belated Valentine’s Day message to him.

She took to Instagram as she publicly expressed her love for him.

“I have learnt a lot and am also learning a lot about myself since meeting you,” she wrote.

“There will always be struggles but as long as that magic and those unforgettable experiences are there it’s all worth it.

“Happy belated Valentine’s. I love you.”
