Tim Tszyu's wife has revealed where the pair first met and has also opened up on their first date.

The Australian boxer and his long-time partner Alexandra Constantine were married earlier this year in an intimate ceremony in front of 120 guests in Sydney's east.

The 30-year-old boxer, who is coming off the back of two straight losses, is due to face Joey Spencer on April 6 in Newcastle and is hoping to turn his indifferent fight record around with a win.

But ahead of his fight, Constantine, speaking to Phil Rothfield of the Daily Telegraph, has lifted the lid on their relationship, revealing that they met after she attended a gym class that Tszyu was leading.

'We met at Tim’s gym down at PCYC Rockdale just after his first professional fight (December 2016),' she said.

'One of my girlfriends, who he grew up with, took me along to a class there. He was running the gym at the time and was taking the class I was doing.

'I developed a really close relationship with him after that.'

Constantine has been by Tszyu's side throughout his career with the couple meeting back in 2016.

Constantine, a Sydney-born finance graduate, is fluent in three languages - Macedonian, English and French. She attended the University of Technology in Sydney before pursuing a career in property law.

She also lifted the lid on their first date.

'We played arcade games at Timezone, then had a late meal at Cosmopolitan Café in Double Bay,' she added.

'Tim said he thought I was trying to impress him by taking him there… but they seriously had the best schnitzel and mash going for years.'

Constantine has regularly attended Tszyu's fights in the past but at home, she revealed the chores her husband does around the house.

'He just brings the chaos,' she added.

Tszyu is hoping to get back to winning ways and has been called out by multiple fighters including long-time rival Michael Zerafa and Keith Thurman.

His upcoming opponent, Spencer, has lost once in 19 fights, with that defeat coming against Jesus Alejandro Ramos Jr back in 2023.

But with Tszyu in camp ahead of what might be one of the most important fights of his career, he and Constantine still have plenty of time to catch up.

'Now he is in camp in Sydney, we see each other daily – aside from when I need to go into the office for work; we are passing ships in the night,' she added.

'This camp we have been going to Cronulla after dinner, walking past Anita Gelato and talking about how many scoops and which flavourings we will enjoy post-fight.'
