Jackie ‘O’ Henderson has undergone a dramatic weight loss transformation within the last year. 

The radio titan opted to flaunt her new killer curves on Thursday when she hit Clovelly Beach in Sydney’s Eastern Suburbs.

The 49-year-old looked fighting fit at the seaside playground favoured by influencers and former reality stars.

Jackie donned a navy ensemble for her fun in the sun, which consisted of a low-cut bikini top with white piping that showed off her ample bust.

She completed the look with a modest skirt, and wore a white knit vest over the top.

Jackie ensured all eyes were on her when she slipped off her vest, threw her headwear to the wind and stepped into the water for a refreshing dip.

She appeared to be enjoying her solo time as she paddled about in the ocean. 

Jackie has shed a whopping 18kg in the space of less than a year and recently revealed the exact amount she weighed before deciding to embark on her weight loss journey. 

She made the confession during The Kyle And Jackie O Show after the radio program welcomed a caller on-air who weighed 85kg. 

Curious newsreader Brooklyn Ross turned to Jackie and asked her, ‘Do you know what the biggest [you weighed] was?’ 

‘The biggest was 80’, she replied.

Jackie’s admission comes after she was once forced to deny that Ozempic is behind her spectacular slim down.

Ozempic, an appetite suppressant previously used to treat Diabetes type II, has seen an increase in prescriptions for obesity in recent years and is now used by many celebrities to keep a trim figure.

Jackie has always insisted she achieved her weight loss by going on WW (Weight Watchers), which she was an official ambassador for.

When asked what her heaviest weight was, Jackie revealed it was 80kg. Pictured in October last year 2022 with Kyle Sandilands

But speculation kicked off again after WW, under the leadership of CEO Sima Sistani, has started to embrace semaglutide drugs like Ozempic.

Reacting to the news on the The Kyle and Jackie O Show, Jackie exclaimed, ‘That makes it look like I was definitely on Ozempic!’

She jokingly added, ‘I was like a guinea pig in that experiment.’

Newsreader Brooklyn Ross then asked Jackie if she was ‘annoyed’ she had to lose weight ‘the hard way’ instead of just using a semaglutide for a quick fix.

‘I mean, they make a good point and I’m really impressed that they’re with the times,’ she said.

‘You see so many people doing it and being successful and it not really being that hard for them.’
