However they were spotted looking loved up at Melbourne Park last week, seemingly putting the rumours to bed.
Kyrgios also posted a sweet message to Passari on a camera lens at the Australian Open, while she gushed about her man in a cute Valentine's Day post.
“I have learnt a lot and am also learning a lot about myself since meeting you,” she wrote alongside a photo of the pair.
“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.”
But in a fresh twist, Passari has seemingly alluded to more trouble in paradise.
Posting a photo of herself laughing while watching Kyrgios from the stands at the Australian Open, Passari wrote: "Laughing at myself for believing a..."
She also reportedly asked her followers if anyone had attended Melbourne nightclub OneSixOne in the past three weeks, where Kyrgios posted a photo from last week.
Passari has also deleted her Valentine's Day message to Kyrgios.
Latest twist in Nick Kyrgios' relationship dramas
The latest twist follows weeks of drama surrounding Kyrgios and Passari.
Before the Australian Open kicked off, Passari posted: “Cheaters always want you to be loyal while they’re being unfaithful."
Kyrgios then further fuelled the rumour mill when he appeared to delete a number of photos of Passari from his own Instagram page.
But Passari was then spotted in the stands at the Australian Open and courtside as he practiced last weekend.
Passari wasn't in attendance for his opening two matches, and the World No.47 was clearly missing her.
“Miss u Chizzel,” he wrote on a courside camera lens after his opening round victory.
The Australian star also referenced Passari in his post-match press conference after losing in the third round.
“At the end of the day I know it's just a tennis match. I mean obviously I'm going to get angry as I'm playing. I'm a competitor, I want to win," he said.
“But I don't beat myself up over losses. I'm extremely lucky to even be in my position.
“I’m healthy, I've got great friends, great family. I've got an amazing girlfriend back home."
Kyrgios and Passari have been together since last year.
He previously dated fellow players Ajla Tomljanovic and Anna Kalinskaya.
