She was quickly dubbed the 'hot bride' by fans on this year's season of Married At First Sight.
And speaking to Daily Mail Australia this week to promote her online dance workouts, Kasey 'KC' Osborne revealed her balanced approach to diet and exercise.
The 31-year-old said she eats healthily '70 per cent' of the time, allowing herself to indulge in junk food on Sundays.

'My diet is mostly 70 per cent healthy eating and 30 per cent naughty food,' KC told Daily Mail Australia.
'I like to eat healthy, not just for my body but for my skin. As far as the naughty food goes, I try not to feel guilty as you still have to enjoy yourself.'
KC said she eats sushi 'the most' and has her cheat meals on Sundays.
Not as strict as you would think: 'My diet is mostly 70 per cent healthy eating and 30 per cent naughty food,' KC told Daily Mail Australia
'Eating well makes you feel better': KC allows herself to indulge in junk food on Sundays, but encouraged 'eating well, because it's not just about what you look like, it's about how you feel'
'I think it's normal if you want to eat like that from time to time,' she said. 'However, I definitely encourage eating well, because it's not just about what you look like. It's about how you feel. Eating well always makes you feel better.'
KC maintains her washboard stomach with hot yoga and ab workouts in her dance classes, and joked that she's yet to turn boyfriend Michael Goonan into a dancer.
'The response to the classes has been absolutely amazing,' she said. 'The messages I have been getting from participants has been positive, and helped put a smile on people's faces during this time.'
