Radio star Jackie 'O' Henderson keeps it effortlessly cool in a Johnny Cash T-shirt and denim cut-offs during Sydney stroll

She's learned the secret to defying time when it comes to her appearance.

And Jackie 'O' Henderson, 51, looked every inch the ageless beauty on Wednesday when she was spotted out and about in Bondi Beach in Sydney.

The KIIS FM radio star cut a relaxed figure in a blue rock 'n' roll Johnny Cash T-shirt, which she wore loosely over a pair of white denim cut-off shorts.

Jackie showcased her toned pins as she strolled along the street, flashing her best angles while soaking up the coastal sunshine.

The blonde broadcaster completed her off-duty look with Adidas sneakers, oversized sunglasses and a striking red designer clutch slung casually over her shoulder.

She styled her hair in soft, tousled layers and appeared in high spirits as she walked with a coffee and her smartphone in hand.

Jackie looked effortlessly youthful during the outing, continuing her run of low-key yet stylish public appearances. 

The media personality famously revealed in 2023 that she had lost 18kg, and has maintained her slim figure ever since. 

The youthful star has previously admitted to having some cosmetic procedures to maintain her visage. 

Jackie confessed to her co-workers at The Kyle and Jackie O Show that she occasionally gets Botox.

'I just get Botox. I've gotten lucky with that. I do have lines though. I definitely do,' she said, adding that she has smile lines.

In addition to using Botox, which removes wrinkles by temporarily paralysing facial muscles, Jackie has been known to splash out on various spa treatments. 

She has been known to visit the Venustus day spa in Paddington, Sydney, where she enjoys a two-hour package worth $707.

The veteran presenter explained she opted for the Intuitive Package, which included breath work, a massage and a sound bath. 

The massage alone is priced at $353 while the two-hour package, which Jackie took part in, comes to $707.

'Treating myself to a full body reset,' she wrote in one Instagram caption, adding in another she was 'a sucker for a sound bath'.

A sound bath is a meditative practice where instruments such as gongs, chimes and singing bowls are used to soothe.

Last year, Jackie also revealed another pricey product she includes in her skincare regime.

Jackie and her co-host Kyle Sandilands interviewed Savage Garden frontman Darren Hayes and commented on how good his complexion was.

Darren said he uses collagen face masks from popular Japanese skincare brand SK-II.

Jackie remarked she now uses the very same face masks to keep her youthful skin, exclaiming: 'Those are the ones I use, I love those!'

It is hardly a budget beauty secret, as the brand's facial treatment masks cost a staggering $159 for a pack of six.
