While many Aussies bundle up to stay warm from the chilly winter breeze, across the ocean in America, Sharon Stone is showing everyone that she is ready for the summer sun with a sizzling hot new bikini selfie.

On Wednesday, May 24, the 65-year-old Basic Instinct star left the internet in a stir after sharing a photo of herself posing in front of a mirror wearing a very daring green cheetah print string bikini with matching thong bottom.

“Ready for summer,” the mother of three captioned the shot.

Many of Stone’s fans quickly flooded her post’s comment section to share their thoughts on her latest selfie.

“More like Sharon Stonecold FOX!”

“Whawhawhawhawowza!!!”

“Beautiful and natural! Unlike all those pumped and filters images around! @sharonstone always inspirational”

“I don’t think you’ve ever been more sensual.”

But not everyone was impressed with the shot, with some users simply saying “nope” and others asking “why” she felt the need to share the photo.

“For whom and why this photo? …..I am sorry …. SS you don’t need this.”

However, Stone’s fans were quick to squash the haters and praised her for her beautiful physique.

“Sharon you look fantastic for ANY age. Keep doing you and don’t listen to any haters. You look fantastic and fit and healthy.”

“If your mouth can’t say anything good or kind, instead of talking nonsense, say nothing.”

Stone appears to be making a habit of sharing sizzling swimsuit snaps. Her latest shot comes after she stunned fans with an equally impressive photo of herself rocking a plunging one-piece swimsuit.

The actress was enjoying a “Sunday Funday” with her pals, candle designer Tina Manning, Jennifer Lazarus and stylist Brandy Snow during a pool party at her Beverly Hills home.

Last year, Stone sent fans into a frenzy with a topless bikini snap, sharing the stunning image of herself on Instagram wearing nothing but leopard print bikini bottoms and a towel tastefully draped over her chest.

In addition to her posts promoting body positivity, the actress has also been a vocal advocate for women’s health, taking to Twitter to encourage women to take action when it comes to their health after undergoing the wrong procedure for a misdiagnosed tumour.

Since then, the actress has maintained a low profile, keeping fans updated with her life by occasionally sharing photos of her family or her art on her Instagram page.
