Jackie ‘O’ Henderson stuns in a rare swimsuit photo that shows off her 18kg weight loss

Jackie ‘O’ Henderson continues to show off her impressive body transformation.

The radio presenter, 48, stunned fans and followers when she posed in a rare swimsuit photo amongst several photos from her recent holiday in the South of France.

Jackie looked fabulous in the black one-piece suit that accentuated her figure with side cutouts.

The blonde had her hair pulled out and sunglasses on as she stood thigh-high in the crystal clear ocean.

“Week 1 – South of France,” she captioned the post.

Several friends and fans responded to the comments to share their praise for Jackie’s stunning new look.

“That bathing suit!” actress Rebecca Gibney wrote.

“Beautiful treasure!” fitness trainer Michelle Bridges added.

“You look breathtaking!” another noted.

Jackie also shared several other photos from the recent vacation, which included walking the streets of Saint Tropez in vibrant floral dresses and sweet snaps with her daughter Kitty, 12, and Kyle and Jackie O’s radio team.

She also had a girls’ day out with Kitty and KIIS FM producer Jaimee ‘Mayo’ Hassos, plus her co-host Kyle Sandilands and his wife Tegan Kynaston for their honeymoon.

It comes after Jackie recently revealed her updated day on a board.

She told Sunrise earlier this month that she indulges in a range of healthy meals packed with protein, fruits and veggies.

‘[For breakfast] I’m trying to make a smoothie that just has a lot of fruits and vegetables that I need,” she explained.

‘During the day it can be anything from soup to salad. I absolutely love salads.’

The Weight Watchers ambassador said she prepares dishes for dinner with “vegetables and protein” that are easy to pop in the oven after a long day.

She also uses many Weight Watchers recipes for inspiration.

It comes after Jackie revealed her cup size live on The Kyle & Jackie O Show on Monday morning.

Jackie admitted that she is now a C cup size, but did not reveal her under bust size.

The blonde beauty hit back at co-host Kyle Sandilands, 51, when he said she was “back as a normal, acceptable weight.”

“What a terrible thing to say, Kyle. Any weight is acceptable,’ Jackie objected.

“You can’t say that something is acceptable in terms of weight. Those are old-fashioned standards you have there.’

Jackie recently revealed that she lost a whopping 18kg in just five months, but was forced to quash rumors that it was due to using a celebrity weight-loss drug.

Many speculated she was on Ozempic, but last month Jackie revealed she lost weight the old-fashioned way: by following a low-calorie diet, exercising regularly, and avoiding alcohol.

“The diabetes meds people talk about, I don’t take them,” Jackie replied.

“Honestly, you guys can do it… but I’ll say it, I think [cutting out] alcohol and exercise was a big thing. I never did [that] before, so that was kind of the kicker for me.”

Jackie, who recently started playing tennis regularly, added that quitting alcohol and embracing exercise was ‘great’ [she’d] never done before’.

The mother of one of them also confirmed that she didn’t even drink alcohol at Kyle’s wedding in April.

Jackie also recently spoke about her new diet on The Kyle and Jackie O Show, revealing that she often skips breakfast, a practice known as intermittent fasting.

She also avoids carbs and satisfies her hunger throughout the day by snacking on pre-cut pieces of steak.
