The 30-year-old sent pulses racing as she donned a racy khaki PVC jacket with embroidered detailing for the photo.

Sporting a tight-fitting skirt to match, the singer teased fans with a glimpse of her svelte physique.

Opting for an effortlessly chic look, she teamed the racy get-up with a pale pink t-shirt.

Beside the upload, The Saturdays star wrote: “Khaki malarkey.”

Running a hand through her hair, the blonde beauty let her golden locks fall over her shoulders in loose curls.

The former Strictly Come Dancing  contestant opted for shimmering gold eye-shadow and pink lipstick, and accentuated her long lashes with a touch of mascara.

Flashing her pearly white teeth, the popstar smiled at the ground for the candid snap.

Mollie’s 757,000 followers were driven wild by the photo with one simply writing: “Incredible.”

Another supporter told the London-born star that she was “beautiful, inside and out”.

A third admirer gushed: “Everyday you slay me more. You’re so gorgeous it’s actually insane.”

The photo came just days after the Ego singer allegedly enjoyed a romantic getaway with Strictly professional AJ.

Fans speculated that the pair were spending the weekend together after Mollie shared a series of photos of herself at a luxurious spa hotel.

In one seriously sexy shot, the vocalist flashed a hint of sideboob as she posed in nothing but a revealing red one-piece.

And, while the TV star was pictured on her own in each photo, her rumoured beau soon had fans convinced that they were together, after he shared his own swimming pool snap.

The 23-year-old dancer told followers that he had been for a “gym and swim”, before stripping off to reveal his rippling abs.

The duo, who were rumoured to be dating last year after meeting on the BBC One show have denied that they’re more than friends.
