BRITTNY WARD regularly flashes the flesh online, but she took things to a whole new level today as she seemingly went knickerless for one of her sexiest snaps to date.

dtThe girlfriend of Formula One champ Jenson Button treated her 278,000 Instagram followers to yet another sizzling shot, with her lying down on a sun lounger and showing off her incredibly pert derrière.

Brittny donned a sexy grey top and she tied a striped blue and white shirt loosely around her waist, with her highlighting her toned pins by posing with one leg bent.

uuThe brunette lay down on her side and she gazed seductively over her shoulder, with her perfecting her pout for the camera and putting her hands above her head.

duUnsurprisingly, the photograph went down an absolute storm with Brittny’s fans, with one person posting: “Hot sexy babe,” as a second gushed: “Great body.”

faBrittny’s latest post comes after she took to her profile to flaunt her bikini body once again, with her flashing some serious sideboob in a pale pink two piece.

Brittny posed up a storm in the daring ensemble, which clearly struggled to contain her ample assets.

ccThe stunner also highlighted her washboard abs in the barely-there get-up, that also featured a pair of skimpy bottoms with see-through sides.

Brittny looked provocatively away from the camera, with her covering her eyes with a pair of round white-rimmed sunglasses and she wore her locks in tousled waves cascading over her shoulders.
