Brittny, 25, teased her 280,000 followers with a saucy snap of her pert behind as she stripped down to a revealing pink two-piece.
Posing side-on, the brunette bombshell flaunted her pert posterior in the barely-there number, which featured see-through plastic straps creating an almost nude illusion.
The sexy snap showcased the tanned model’s slender pins, cropping to just show from her shoulders down, as she clasped a matching pink jacket.
Brittny, who has been dating Formula One star Jenson Button, 37, for over a year, whipped her fans into a frenzy with the racy snap, as they rushed to the comments section to gush over her enviably toned figure.
“Love everything about this. But mostly your body,” said one social media user, while another simply added: “Amazing!”
A third fan complimented the beauty on her bikini, which is from her new Girls On Swim range, saying: “That’s some sexy swimwear.”
Brittny is no stranger to sharing revealing snaps with her social media fan base, and she recently treated her Instagram followers to a series of very saucy clips as she worked up a sweat in some racy gym gear.
Sharing three steamy videos, she flashed her ample assets in a daringly low-cut thong bodysuit with strap detailing, giving her followers a glimpse of her peachy behind, lifting a tire and working out her arms as she straddled a bench provocatively.
The second clip showed Brittny in a busty sports bra, getting in the ring for some boxing training before taking a break and dripping water over her cleavage from a bottle.
The third saw yet another outfit change as she swapped in a plunging grey bra and a pair of bottom-baring black knickers as she posed for some more sexy and sweaty shots.
