An Australian tennis ace has split from his Melbourne model girlfriend after only 18 months together.

Glamour couple Thanasi Kokkinakis and Hannah Dal Sasso quietly called it quits recently when they stopped following each other on Instagram. 

The pair spent a year and a half together and maintained a long distance relationship as the professional athlete, 28, often travelled for his tennis career.

Influencer Hannah was last seen with Thanasi in July during Wimbledon and travelled with him for part of the US tournament season. 

However, it seems the pair have finally called time on their relationship after debuting together during Glamour on the Grid in Melbourne last March. 

Hannah, who runs designer clothing hire company Styled by Mim, said at the time she and Thanasi met ‘a few months ago’ and had been travelling together ‘for a bit’.

She revealed in May this year she isn’t keen on the term WAG, an acronym used for wives and girlfriends of professional athletes.

The Melbourne It girl preferred to be known for her own merits, rather than being someone’s partner.

‘I know in footy there are so many girlfriends and they get called WAGs, but in tennis there aren’t many and you never really see someone called that,’ she said.

‘I like having my own name and not being someone else’s partner.’

Hannah also discussed with Herald Sun the challenges of maintaining a long-distance relationship while Thanasi travels the globe with his tennis career.

‘We just had a nice month together and I already miss him – long distance is really hard,’ Hannah told the publication.

‘Thanasi is really dedicated to his tennis and he’s putting everything into it and I’m so proud of him.’

Last May, Thanasi paid tribute to Hannah after scoring his first win at the French Open, admitting she was his ‘first girlfriend, probably ever’.

‘[I’m a] late bloomer, I guess you could say, so I’m trying that, but that brings its challenges as well. But she has been great,’ he said.

The couple sparked split rumours late last year after Thanasi was spotted on celebrity dating app Raya, but appeared to reunite ahead of Wimbledon. 

Just days earlier, Thanasi was spotted at the Piper-Heidsieck Summer of Tennis launch in Melbourne without his model girlfriend by his side. 

At the time, they hadn’t been photographed together since June last year when they went on a double date with friends Nick Kyrgios and his girlfriend Costeen Hatzi. 

Daily Mail Australia has reached out to Thanasi and Hanna for comment.
