The model - who is dating actor Jason Statham - oozed effortless cool in her chic yet simple ensemble while touching down at LAX airport amid a flurry of photographers.
Rosie has an off-duty wardrobe to die for and we heart her latest look, with the starlet teetering along in a fab pair of pointed ankle boots complete with fringed detailing and silver embellishment.
She flaunted her supermodel pins by sporting super-tight indigo jeans, adding a loose-fit black knit to help keep herself cosy during the long-haul flight.
Rosie recently cut her Goldilocks tresses into a long bob, and she wore her glossy hairdo in a sleek and straight style while shielding her peepers with oversized sunnies.
But the pièce de résistance of her look had to her swoon-worthy designer arm candy! She opted for the lavish Saint Laurent Sac de Jour as her hand luggage of choice (in case you're wondering, her bag retails at well over £1,500... eeek!).
The blonde bombshell was heading back to LA after enjoying a few days in England to promote her new fragrance, Rosie for Autograph.
Rosie first attended a swanky launch party for the scent at Hotel Café Royal before posing up a storm at a photocall the next day, looking oh-so-glamorous in a silky nightie.
Her debut perfume is a floral-oriented scent boasting heart notes of rose, magnolia and jasmine along with a lingering base of sandalwood, vanilla and musk.
