Justin Bieber's ex writhes topless for thong exposé

The social media sensation shot to fame in August last year when she and her then-fling Justin Bieber were spotted skinny dipping in Hawaii.

Now, the blonde beauty has once again taken to the official Sahara Ray Instagram account to keep her besotted followers wanting more.

Sharing a raunchy snap of herself sprawled across her bed wearing nothing but a thong, the blonde was seen modelling only half of her swimwear collection.

Posting the X-rated snap was risky business for the bombshell as she tip toed around Instagram's nudity policy once more.

Cosying up to a cuddly bear toy, the starlet left very little to the imagination as she posed in the teeny black number.

Naturally, the saucy picture has proved to be a huge success with the Insta-babe's 1.3 million followers, racking up a huge 49,000 likes.

It didn't take long for Sahara's legions of fans to start gushing over the smokin' hot snap, with one gushing: "Wish I could be the big spoon beautiful Sahara Ray."

Another excitable admired replied: "OMG your body."

While a third added: "My kind of girl."

Sahara first hit headlines during her topless exposé with Justin Bieber.

At the time, the 24-year-old model posed for a number of eye-watering snaps as she relaxed in the sunshine.

Now, she's amassed over 1 million followers and cannot stop teasing her fans.
