Jackie O shows off her cleavage as she flaunts her 18kg weight loss in a low-cut dress

Jackie ‘O’ Henderson is currently living her best life in the South of France as she experiences her co-host Kyle Sandilands’ honeymoon.

And the mother of one, 48, has been serving up chic looks as she enjoys her lavish trip to Saint-Tropez.

In a video posted to the Kyle and Jackie O Show Instagram page, the blonde beauty showed off her ample cleavage in a chic low-cut dress.

The radio host recently admitted she’s dropped to a C-cup in bras after she lost a whopping 18kg in just five months.

For her lunch outing, Jackie appeared to be wearing a low-cut, white-patterned summer dress by Zimmermann.

She kept her long light locks in a loose curl and she opted for a dewy makeup look with bright pink lips.

The radio host wore black Ray-Ban sunglasses as she sipped her coffee in the sun.

Many people have speculated that Jackie is on Ozempic and that is why she lost weight so quickly.

The drug has taken the showbiz world by storm and many celebrities have been accused of taking it.

Although it is mainly used as an anti-diabetic drug, it also helps obese people for long-term weight management.

Last month, however, Jackie put those rumors to rest, revealing that she lost weight the old-fashioned way: by following a low-calorie diet, exercising regularly, and abstaining from 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.”

The child’s mother confirmed that she didn’t even drink alcohol at Kyle’s wedding in April.
