The Page 3 star and loaded legend treated her 129,000 followers to a racy snap on the social media site last night.
The picture – which sees Rhian pose in strappy black bra and knickers – was taken behind the scenes while the model was taking part in a glamour shoot.
Rhian looks incredible in the post, and it’s already racked up thousands of likes.
It’s a stunning photo, and proves why Rhian is one of the hottest models on Instagram at the moment.
“#BTS of today’s shoot!” Rhian captioned the picture, which has picked up hundreds of comments from fans.
“So gorgeous,” one wrote, while another added: “Beautiful as ever.”
Rhian’s in amazing shape, most likely thanks to a dedicated fitness regime. Keeping her followers up to speed with her workouts, the model posted a picture of herself in skimpy gym wear.
She wrote: “#GymBrag. I feel it’s acceptable to gym brag when it’s a new fitness regime and it took every ounce of effort in me just to get there!”
These aren’t the only images she’s posted on the site recently either. Rhian has been back in the limelight after posting a series of incredible snaps recently.
