Nick Kyrgios spotted with girlfriend Chiara Passari at Australian Open

Nick Kyrgios has been spotted at the Australian Open with his girlfriend, spending Valentine's Day with Chiara Passari at Melbourne Park.

Ahead of his second-round match with Thanasi Kokkinakis in the men's doubles, Passari was spotted courtside watching Kyrgios practice.

Channel Nine cameras spotted the moment Kyrgios planted a kiss on Passari as he made his way to his courtside seat.

"She doesn't look too impressed, didn't even pull the mask down," Clint Stanaway said on Channel Nine's coverage.

Stanaway then made a cheeky reference to co-commentator Tony Jones' infamous kiss fail with Rebecca Judd, as you can see in the player below:

"I'm not one to comment on awkward kisses on air," Jones said in reference to the mortifying moment Judd recoiled as he tried to plant one on her cheek during a Channel Nine news bulletin.

Passari wasn't at Melbourne Park earlier in the tournament, but flew in before Kyrgios' third-round clash with Dominic Thiem.

She is believed to have joined him in quarantine before Victoria went back into a five-day lockdown on Saturday morning, explaining why she is allowed to be out on the practice court with him.

Fans have been locked out of Melbourne Park until Thursday after Victoria was plunged back into a stage four lockdown.

Nick Kyrgios smacks down ugly break-up rumours

Kyrgios put to bed rumours of trouble in paradise with his girlfriend when he wrote a sweet message to Passari after his win in the first round on Monday night.

Passari sparked some ugly rumours last week with a cryptic post about “cheaters” on her Instagram page.

“Cheaters always want you to be loyal while they’re being unfaithful,” she wrote without mentioning Kyrgios.

Passari added: “It keeps getting better y’all.”

There were also some bizarre media reports that Kyrgios had deleted all photos with Passari from his own Instagram page, despite there still being multiple for fans to see.

On Monday night, Kyrgios put the ugly rumours to bed by writing a message to Passari on a TV camera on Rod Laver Arena.

“Miss u Chizzel,” he wrote on the lens, along with a smiley face.

He later posted a photo of himself writing the message, tagging his girlfriend in the post.

Kyrgios also referenced Passari in his post-match press conference.

“I feel old. I feel like this sport has stressed me out. I feel like an old soul,” he said.

“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.

“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 Kokkinakis will take on fourth-seeded Wesley Koolhof and Lukasz Kubot on Sunday for a place in the third round.
