The Big Brother host, 57, has proved you don’t need to be young to show off your figure.
Wearing a tiny string triangle bikini with a cute blue pattern, the star looked relaxed in the snap.
Wearing an open blue shirt, bare feet and a pair of sunnies, Sonia is the picture of summer.
In her caption, she shared her secret to the perfect tan with her followers.
“No sun, no worries! Three Warriors has you covered all year round. La Niña? More like, La Bikiña!” she quipped.
The Voice Australia host is a ‘tan ambassador’ with the Three Warriors skincare line, created by Aussie hair stylist Corbin Halliday.
Sonia’s ‘Golden Glow Pack’ retails on the site for $152.70, but is currently on special for $139.95.
The pack includes an exfoliating glove and four tanning products made from local Tasmanian ingredients.
“Used this two nights ago! You’d kindly gifted me some a while back. Too cold to use. It’s warming up so I used the mousse first and then last night topped up with gradual tan. Really loved it. Good colour and no streaking using the mit. Thanks Sonia,” Kylie wrote.
“Love this product! Especially the gradual tan,” added Sunrise star Sarah Di Lorenzo.
“I have seen a few Three Warriors shows on TVSN — looks and sounds amazing. Seriously need to try it!” a fan chimed in.
Other fans couldn’t get over Sonia’s incredible bikini body, with a fan calling her ‘gorgeous’.
“Oh wow! You look just absolutely sensational,” a second wrote.
“Look at that bodyyyyy,” added a third.
“You are stunning Sonia. I want to be you when I grow up (I’m 40 but that’s irrelevant),” another quipped.
“Just one word Sonia. WOW. You look beautiful. You’ve definitely still got it girl,” remarked another.
