Sonia Kruger, 58, and Kerri-Anne Kennerley, 70, show off their ageless beauty as they lead the arrivals at Sydney’s Women in Business luncheon

Sonia Kruger and Kerri-Anne Kennerly showed off their ageless beauty as they stepped out for lunch in Sydney on Wednesday.

The pair pulled out all the stops as they led the arrivals at the annual Mercedes-Benz Sydney Women in Business event, with this year’s theme exploring timeless classics – embracing femininity at any age.

The Voice Australia’s Sonia, 58, looked gorgeous and incredibly youthful in an all-white monochrome outfit as she took on hosting duties.

She made sure she turned heads in a stylish blazer and matching tailored white trousers from Melbourne designer Viktoria & Woods.

She paired the chic suit with a sheer white corset and see-through perspex heels.

Sonia accessorized with a few pieces of silver jewelry, including a series of chunky rings and a simple watch.

The media personality, who shares daughter Maggie with her long-term partner, former 7 News director Craig McPherson, let her natural beauty shine through with a nude lip and bronzed eyeshadow.

She twisted her blonde locks into soft curls that fell around her shoulders.

Hottest with the Most Woman Sonia welcomed guests to the event with some inspiring words and some absolute zingers, including a joke about being Rupert Murdoch’s ‘third wife’.

She then compared the beauty of a brand new Mercedes-Benz to her handsome Dancing with the Stars co-host Dr. Chris Brown.

“…I love being a friend of his because let’s face it, everyone wants that handsome friend who has style and class that they like to be seen with in public,” she said.

“For me, it’s a bit like being friends with Dr. Chris Brown, but I can’t lock him in my garage at night.”

Sonia then shared her top tips for success with a touch of satire.

“To find success you need to follow a few simple steps, these have always worked for me,” she told the audience.

‘Number one: you catch more flies with honey than with vinegar.

“Number two: be the visionary. Did anyone say to Marie Curie, don’t worry about what your husband will say? Of course not.’

“Number three: You don’t need male approval, so don’t look for it.

“I imagine the last man who told a woman to calm down is still eating lunch with a straw,” she said, causing the crowd to laugh.

“Number four: work-life balance,” she added.
