Whitney, who rose to fame when she starred opposite Lauren Conrad in The Hills, wore her dark hair in a bun.

Her curls were neatly swept up and arranged in an imperfect bun on top of her head.

She skipped earrings but wore a chain around her neck and several rings on her fingers while sipping from a plastic cup.
