At the grand old age of 69, Maye Musk (above), mother of inventor- entrepreneur Elon, is having a moment. A mother of three and grandmother of 10, the silver-haired siren with luminous skin is walking tall alongside a bevy of younger models at New York Fashion Week. She signed recently with IMG - one of the most prestigious modelling agencies in the world - and starred in a show of young South Korean designers last Friday. She has developed something of a following in South Korea since she graced the cover of Vogue Korea.
