They're both fans of the polished and put-together look, their favourite beauty addition is always a glossy mane - and after seeing both style mavens working the animal print trend, we reckon Olivia Palermo could be Rose Byrne's style twin.

Rose, normally a fan of a feminine mini dress for the red carpet, opted for a cool ensemble of skinny black trousers, high heeled pumps and a statement black and white leopard print oversized coat. Utterly effortless, Rose wore her long bob swept to the side with a nonchalant slick of postbox-red lip colour, perfecting her chic style for the after-party of the I'm So Excited film screening.

Meanwhile, fashionista Olivia was attending the SKYY Vodka Governor's Ball Kick-Off party. Known for her keen ability to pair together separates, Olivia styled a sleek sequin Diane von Furstenberg blazer with an armful of bangles, some snakeskin flats and her classic Givenchy Antigona bag. Her piece de resistance which added a fierce edge to her outfit, however, was a monochrome zebra print skirt - from none other than her high street favourite, Zara.
