Dannii Minogue looks half her age as she shows off her completely line-free visage at Jamie Oliver event

Dannii Minogue stunned with her ageless beauty as she led arrivals at a Jamie Oliver event in Sydney .

The pop star, 53, looked half her age as she walked the red carpet at the inaugural Jamie Oliver Food Hero Awards.

The younger sister of pop princess Kylie Minogue wore a gorgeous spearmint-coloured frock with exquisite detailing reminiscent of flowers and plants.

The outfit's also featured glamorous jewel-encrusted trimmings at the waist and at the shoulder straps.

Dannii went for a bronzed makeup look as she worked her angles on the red carpet, and not one line could be seen on the 53-year-old's face.

She wore her long hair down, and it tumbled over her shoulders in loosely curled strands.

The former Masked Singer Australia panellist completed her look with a pair of silver, strappy heels.

After the photo opp, Dannii boarded Royal Caribbean's cruise ship, Ovation of the Seas, currently berthed at Circular Quay, where the awards show was held.

It comes after Dannii was spotted jetting off on a holiday with her rarely-seen son Ethan and her boyfriend Adrian earlier this year .

The Love and Kisses singer had her hands full with luggage as she made her way to check in after arriving at Sydney Airport.

Dannii welcomed her son, now 14, with former rugby league player Kris Smith back in 2010.

The pair dated 2008 to 2012 after meeting in Ibiza in 2008 while he was celebrating his 30th birthday.

Ethan has remained largely out of the spotlight throughout his childhood and Dannii previously said her son didn't know she was a pop star.

Dannii and Adrian also famously keep their romance under wraps and rarely speak about each other publicly.

Earlier this year, Dannii gave a rare insight into their low-key romance and opened up on the prospect of marriage.

Of keeping their relationship out of the limelight, she told Hello: 'I haven't always been able to do it that way before because if the other person is already famous, then what can you do? But he works behind the scenes, so it's easy.'

'Marriage isn't on the cards, but we're just enjoying growing up together and spending time,' she added.
