The sexy blonde turned heads as she arrived at the event in her daring outfit, showing a lot of front as she leaned forward getting out of her vehicle.
She finished her look with a slick of pink lipstick, a dark red clutch, gold hoop earrings and a pair of sunglasses, wearing her hair in tousled waves across her shoulders.

Katy Perry meanwhile went for a more conservative look, in a semi-sheer white dotted Victorian-style frock with a high neckline and layers of ruffles.
She wore her hair parted sharply in the middle and slicked back in a ponytail at the nape of her neck.
Model Rosie Huntington-Whitely rocked a menswear-inspired outfit, pairing wide-legged grey pinstripe trousers with a white long-sleeve dress shirt she wore halfway unbuttoned.
