The glamorous bash in Sao Paulo, Brazil, both stars opting for very different looks, but both looking equally stunning.
Unique as ever, Kate plumped for a plunge-neck black frock with an embellished trim and a handkerchief-shaped hemline, finished off with a covetable turquoise necklace, a flawless fan tan, and curly hairdo.
Sharon opted for a more traditional old school Hollywood style in a striking long-sleeved scarlet dress with a deep cowl-neck and a statement neckline, also completing her look with tousled tresses. We'd probably ditch the bag, but perhaps we're nit-picking...
They were joined at the bash by other stars including Fergie and Dita Von Teese.
Who do you think won this fashion round?
