Aleks Markovic called it quits with ex-hubby Ivan Sarakula just three months after filming.
And the 26-year-old blonde bombshell tells us she lost a considerable amount of weight due to the stress that came with a very public split.
"I don't eat when I'm stressed, so the break-up definitely contributed to my extensive weight loss," Aleks admits during our phone catch-up.
"I lost about nine kilos after the show."
The Perth-based real estate agent also credits her pescetarian diet for her hot new bod.
"I don't eat dairy or any meat products," she says.
"I start my day with a soy latte, then I eat my lunch at 12pm which is vegetables and fish. Dinner is the same."
Although she admits that she "hates to exercise", Aleks says she'll make sure she gets in 20 minutes of choreographed dancing at least three times per week.
"It's something I've loved since I was a little girl," she explains. "I'm feeling amazing! I have a better routine now despite being in isolation."
When the show wrapped up, Aleks returned to her family in Perth, while Ivan stayed in Sydney, but they still spoke on the phone every day.
"After we left the show, we were good," Ivan explained.
"We had a little bit of a break to reassess and re-establish things - and there was still a question from Aleks about romance etc - but we did pick things up further down the track. We missed what we had."
Aleks and Ivan spent time in each other's home towns. Ivan got to know Aleks' parents, who said they both welcomed him "with open arms."
"They're beautiful, beautiful people," he enthused.
"I think they were smart to not be involved in the show."
The pair have now decided to go their separate ways.
