The High School Musical star (and bride-to-be!) made sure all eyes were on her as she waltzed down the blue carpet at the star-studded ceremony, which boasted a guestlist filled with her fellow Disney stars including Vanessa Hudgens and Bella Thorne.
Making us swoon with wardrobe envy, Ashley stunned in a form-fitting white frock complete with a wrap-over skirt and halterneck design, covered in a glistening silver leaf print.
The stylista added drama to her ensemble by slipping her feet into an eye-catching pair of strappy metallic sandals, while toting a matching clutch and flaunting a pale nude manicure.
Her blonde locks were straightened for a sleek finish, and she tucked one side of her hair behind her ear to showcase her bling-tastic diamond earrings.
And talking of bling, Ashley made sure her mega-watt engagement ring was on full display as she posed up a storm at the event.
Ashley became engaged to Annie Automatic rocker Christopher French after he romantically proposed at the top of the Empire State Building (aww!) in August last year.
There's still no word on a wedding date yet, although Ashley enjoyed a bachelorette party weekend in Miami back in May, so perhaps she'll be tying the knot this summer?
We hope so - we can't wait to see her wedding dress!
