Sexy cowgirl! Braless Alessandra Ambrosio stuns in leather boots and hat for saucy lingerie shoot

Brazilian fashion model Alessandra Ambrosio set pulses racing as she stripped down to the hip - save for a chic cowboy hat – for a latest photoshoot in Colorado.

Parading her assets in a barely-there ensemble, the brunette beauty grabbed eyeballs during the cowboy-themed outdoor shoot.

Ambrosio has been working for Victoria's Secret for the longest time and most recently was spotted flaunting her modelling skills and curves for the lingerie brand's western-inspired pictures.

While giving a miss to a top for the shoot, the 36-year-old model chose to wear just a nude underwear, accessorised with a super-edgy stetson hat, holster and knee-high boots. And needless to say, the overall look – complemented by her dramatic eyes and lose hairstyle – was nothing less than jaw-dropping.

Clearly, a body-confident Ambrosio had no qualms about going almost naked and strutting around in an outdoor location. But, at the same time, in most of the pictures, the catwalk queen appears to cover up her bare breasts with her hands as she risked an accidental flash of her assets.

And while she hid her modesty, the mother-of-two offered a generous glimpse of her peachy posterior, slipping into a skimpy thong during most of the time of the shoot.

She might be a goddess in front of the lenses, but even Ambrosio has her doubts when it comes to flaunting her body, especially after becoming a mother. "I used to be 100% comfortable on lingerie shoots - then I had a child," she had explained to Net-A-Porter, adding, "Somehow it felt a bit weirder to be in lingerie once I was a mum."

"But I think I have a better body now than before I had kids... it just looks more formed now and I feel better about it than I did," Ambrosio added.
