The Australian beauty was left red-faced when the driver failed to stop for her but she appeared to take it all in her stride as she squeezed out a smile and flexed her hand with total surprise.

The 26-year-old model looked glamorous in her high-waisted denim shorts, which flashed a few inches of her flat tummy, a straw hat, some aviator shades and black converse.

She chucked on a black-and-white kaftan with pretty fringing around the hem to take the edge off the gentle breeze and slid a green bag with a delicate silver chain over her shoulder.

Ashley was out-and-about in the Big Apple with her fiancé Buck Palmer and the pair of them stopped off at a coffee shop to pick up a hot beverage.

The pair - who have been dating for five years - took their relationship to the next level last year when Buck popped the question to the stunner while they were holidaying in the south of France.

The attractive duo swam out to a pontoon off the beach where Buck, also a model, asked for his girlfriend's hand in marriage, offering his grandmother's wedding ring.

The engagement news came as a shock to fans after the couple made the unusual decision to put their romance on a four-month hiatus while they each undertook separate 'spiritual' studies.
