Wearing a nude thong two-piece, the 27-year-old showed off her tanned behind as she paddled in the ocean for the beachside photo.

Parting her legs as she stood, Brittny revealed her slender frame in the barely-there bikini.

Soaking up the sun, the fashion model let her sleek brunette tresses fall over her shoulders in loose curls.

She completed the beach babe look by teaming her ruched, halterneck bikini with soft touches of eye-liner and pale pink lipstick.

Looking over her shoulder, the girlfriend of British racing driver Jenson Button showed off her pearly white teeth as she beamed at the camera.

The Californian beauty, who starred as Playboy’s Miss January 2015, started dating the Formula One Grand Prix winner back in 2016.

Alongside the picture, Brittny, who was the ring girl for Ultimate Fighting Championships in 2010, wrote: “Missing beach days.”

The star shared the sizzling snap on her Instagram account earlier today, sending fans wild.

One follower commented: “You have an amazing smile,” while another added: “Wow you are gorgeous.”

A third person was quick to tag Jenson Button in their comment, writing: “[Jenson Button] you’re a lucky boy!”
