Jackie 'O' Henderson sizzles in yellow swimsuit as she shows off her slender figure in Thailand following dramatic weight loss

As the title of her podcast suggests, Jackie 'O' Henderson is living Her Best Life. 

The Sydney radio queen showed off her style chops on Monday as she took to Instagram to share her weekend in Thailand wearing an eye-popping velvet swimsuit. 

The KIIS FM breakfast host, 49, is enjoying some quality time abroad with her 14-year-old daughter Kitty, who celebrated her birthday in Sydney last week. 

Jackie flaunted her trim pins in an enviable mustard yellow one-piece. 

Despite receiving a dozen or so requests to name the maker of the unique swimsuit, Jackie appears to be gate keeping the information. 

Although she replied to numerous comments left on her post, Jackie turned a blind eye to the fans who asked her to name where the swimsuit was from.  

Her figure-hugging one piece features a sweetheart neckline and a boy short cut that manages to be both attention-grabbing and relatively modest.

'Gorgeous xxx,' Jackie's bestie, designer Pip Edwards commented. 

'Hair goals,' wrote model Simone Holtznagel. 

Hair and make up artist to the stars, Max May, also gave the look his tick of approval.

'Heaven,' he wrote. 

Jackie modelled the cozzies with a snorkel in hand, putting her own spin on the ensemble, reminiscent of the swimsuits worn by American pin-up girls in the 1950s.  

The typically coiffed media identity accessorised her holiday look with a pair of gold-framed sunglasses and a pop of pink lipstick. 

She left her blonde locks in natural beach waves as she posed on the sand, after taking a sight-seeing boat trip through stunning aqua waters. 

Jackie wore a leopard-print slip dress as her beach cover-up, adding a touch of her personal style to the laidback ensemble, while her daughter wore a pair of denim shorts and a green singlet over her bikini.

'This can't be real,' she wrote alongside the carousel of pictures from their snorkelling day trip. 

Jackie has been enjoying her slimmed-down figure to the max since shedding 18 kilos in less than a year.

The media personality has been repeatedly forced to deny allegations of Ozempic use as she continues to flaunt her increasingly trim figure. 

'I can't say it enough that I have not done anything other than just eat well, exercise and give up alcohol,' she said on-air. 

The radio host said she avoids carbohydrates and satiates her hunger throughout the day by snacking on pre-cut pieces of steak on The Kyle and Jackie O Show. 

It comes after Jackie celebrated Kitty's 14th birthday in Sydney on Tuesday, prior to their travels. 

'Happy 14th birthday to the kindest, funniest and most thoughtful girl I know. How did I get so lucky? Love you, Kitty,' Jackie penned alongside an image of her daughter. 

Jackie shares Kitty with her ex-husband Lee Henderson, who she split from in 2018 following a 15-year marriage.
