The question shortly to be on everyone's lips: who is Ruby Jean Wilson? Fortunately we're here to provide you with the answer: she is Marc Jacob’s latest model fixation. He cast her to open and close then she walked for him in Paris for too – and it’s clear that the swinging Sixties, backcombed beehive look that Marc's made his signature this season suits her well.

The 18 year old was born in Scotland, and grew up in Australia. Her friends thought it was ‘pretty obvious’ she had the necessary attributes to be a model, and model agency Priscilla’s in Australia wasted no time in signing her up. She also has representation in London, Paris and New York.

Ruby has walked in numerous other big-name shows – Jeremy Scott and Marchesa, to name a few – since her runway debut in 2010. This season though, she debuted her new platinum blonde locks, having previously been a brunette, which seems to have pushed her into the stratosphere.

What’s next for Ruby? She’s been booked to star in the spring/summer 2013 ad campaign for – who else? - Marc Jacobs, shot by Jurgen Teller. Proof that blondes really do have more fun?
