Jackie ‘O’ Henderson showcases her dramatic 18kg weight loss on the cover of Stellar magazine

She recently shed an impressive 18kg in just a few months as part of a radical body transformation.

And Jackie ‘O’ Henderson is set to showcase her new figure when she graces the cover of Stellar magazine this weekend.

The 49-year-old mother of one wore a little black dress in the stunning cover image.

The garment’s plunging neckline made the most of the KIIS FM radio star’s cleavage. 

Jackie recently stunned her fans with her makeover after dropping almost 20kg. 

The star shared her day on a plate last month. 

She revealed on The Kyle and Jackie O Show she regularly skips breakfast, a practice known as intermittent fasting.

She also avoids carbohydrates, and satiates her hunger throughout the day by snacking on pre-cut pieces of steak.

‘I cook steak and slice it, and then I’ll just have a little sliver of steak if I’m hungry,’ she told her co-host Kyle Sandilands.

Jackie, who is an ambassador for weight loss program WW, resists splurging on high-calorie foods for lunch, opting to eat just ‘three little slivers of steak’ and a few Vietnamese rice paper rolls containing fish and cabbage.

Kyle was shocked by her small portion size, telling her: ‘A dog would eat more!’

For dinner, Jackie usually eats vegetables and a protein such as chicken or red meat.

In between meals, Jackie treats herself to smoothies and Starbucks Frappuccinos, a type of blended ice coffee drink.
