Jackie ‘O’ Henderson was looking slimmer than ever on Monday. 

The 49-year-old tried on a series of outfits from the label run by her best friend, Pip Edwards. 

The radio host modelled a number of the P.E Nation looks, her slimmed down figure looking smaller than ever in the fitted ensembles. 

‘Playing dress up today’ she captioned the series of images which were posted to Instagram Stories. 

Jackie tried on a tight grey top and brown track pants, as well as a ruched cardigan and black slacks. 

She also tested out a pair of wide-legged pants and a tight black top with long sleeves. 

Another chic ensemble included a cropped olive jacket and matching trousers with a white shirt. 

A loose pair of army green track pants was also in the mix, paired with a white fitted top.

The KISS FM star and her designer gal pal have become close friends over the past year, often partying together.  

Jackie has shed a whopping 18kg in the space of less than a year.

She previously admitted the exact amount she weighed before deciding to embark on her weight loss journey.

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

The star’s admission came 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.

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.’
