The Bride Wars actress joined the likes of Kim Kardashian West, Cara Delevingne and Jennifer Lopez as she made an entrance at the 2014 LACMA Art + Film Gala, which honoured artist Barbara Kruger and director Quentin Tarantino.
Pulling out all the stops for the star-studded evening, Kate was pretty as a picture as she dressed up in a stunning pale blush pink gown designed by Gucci.
Her beautiful dress featured a sequin underlay complete with a figure-hugging design and a strapless neckline, along with a sheer mesh overlay which cinched in at the waist and draped over one shoulder.
Kate's fancy frock also boasted a floor-trailing train which added to the Hollywood glamour vibe. We love!
Amping up the sparkle with her choice of accessories, Kate toted a silver clutch bag sprinkled with dazzling gemstones while rocking a diamond-encrusted chain bracelet.
Her blonde locks were styled in super-bouncy curls and she slicked her talons a gunmetal metallic shade, finishing with flawless skin and mega-watt jet black lashes plus a sweep of shimmery silver eyeshadow across her lower lashlines.
We heart her choice of lippy too - a pop of bold fuchsia pink was the perfect choice to help offset her soft, romantic frock.
Good work, Kate!
