The 48-year-old was the belle of the ball, showing off her super slim figure in a stylish red Effie Kats strapless gown.
Jackie has undergone an extraordinary body transformation after she took two months off her top-rated The Kyle and Jackie O show in November last year to recover from long Covid.
She returned to social media on New Year’s Eve last year, posting several photos of her slimmed-down figure in a swimsuit while holidaying with her daughter Kitty in Fiji.
In the caption, the mother-of-one wished her followers a Happy New Year and promoted her partnership with Weight Watchers (WW), saying she was feeling the ‘best she had’ in ‘many years’.

The star’s drastic slim-down became apparent again in February, when she started posting photos of herself with some of the guests on her radio show, including rapper Yung Gravy and Bravo king Andy Cohen.
Jackie beamed in a long-sleeve T-shirt and tiny shorts as she stood next to the American rapper and her co-host Kyle Sandilands.
Just weeks later, the blonde star showed off her slender frame again when she slipped into an oversized blue t-shirt and shorts as she posed alongside US Bravo king, Andy Cohen.
Since then Jackie has lost even more weight, which has led to the blonde being dogged by rumours she is taking the controversial weight-loss drug, Ozempic – of which she has denied.

Last month Jackie complained she was the victim of trolls who claimed she had loss the weight as a result of Ozempic and not diet and exercise.
Speaking on The Kyle and Jackie O Show, she said: ‘When I first lost weight and started to lose weight at the beginning of the year, it was all fine. And then when I lost a little bit more, people were suspicious that it came off very quickly.’
‘And since then I’d say, like, for the last 3 to 4 months, I’ve had people just so steadfast in their belief that I have not lost this the right way and I’ve done something else.’
Jackie insisted while it doesn’t matter how someone loses weight, she did it the healthy way.

‘I can’t say it enough that I have not done anything other than just eat well, exercise and give up alcohol,’ she said.
She explained the biggest change was her mindset, as she had previously struggled to shed unwanted kilos for the past three years because she ‘wasn’t in that right head space.’
‘I just was not motivated and I wasn’t mentally feeling well and so I just wasn’t there. I couldn’t find that motivation within me,’ she explained.
Directly addressing critics who said she was taking Ozempic, Jackie said: ‘That diabetic medication people talk about taking, I don’t take that.’

She has instead said she has stuck to intermittent fasting, zero alcohol and a healthy diet to shed the excess kilograms.
Jackie, who recently started playing tennis regularly, added quitting alcohol and embracing exercise ‘was a big thing [she’d] never done before’.
She also confirmed she didn’t even drink alcohol at Kyle’s wedding in April, choosing to go sober for the lavish occasion.
Jackie also recently spoke about her new diet on The Kyle and Jackie O Show, revealing she often skips breakfast for intermittent fasting.

She avoids carbohydrates, and satiates her hunger throughout the day by snacking on pre-cut pieces of steak.
Jackie recently ended her partnership with WW – formerly Weight Watchers – saying she wanted to move on from weight loss.
Appearing on Sunrise in July, she said: ‘Yeah. I think that [the partnership] has come to a natural end. They were incredible to me and they have helped me so much.’
The radio star went on to say she was broadening her focus in regards to her health after achieving her body goals through the program.
‘The focus for me is not on weight loss. I am really thankful they have helped me a lot,’ Jackie added.
‘I feel like I have my life in a really good place now. Healthy and happy.’
Jackie joined WW for the second time after suffering from her bout of long Covid, which forced her to step down from her radio show in November last year.
Just before she went on hiatus she was open with listeners about her struggle.
‘I’ve been not very well ever since I’ve had Covid… I’ve been struggling with this fatigue,’ she said at the time.
‘I’ve been to the doctor several times and he said because I’ve been pushing myself every day, after the show all I’ve been doing is sleeping and I’m not getting better.’
Jackie went somewhat silent on social media during her break, posting no images to Instagram in November as she worked on her mental and physical health.
