Bio:  Supermodel Elle MacPherson's little sister Mimi is known affectionately in her native Australia these days as 'The Princess Of Whales' for her ecological endeavours, but for celebrity sex tape fans Mimi Macpherson goes down in the list as one of the true pioneers of the genre. Her uncensored hardcore home video romps with former boyfriend Michael Hellwig were among the first X-rated celeb home videos to hit the internet. And quite the little performer Mimi proved to be, masturbating for the camera before taking an enthusiastic several minutes long pounding. The scandal didn't do her any harm. In 2008, Mimi Macpherson became the 'face' of the cosmetics firm Evolve Make Up. She has been a presenter for the Discovery Channel in the US and in 2007 she got to the semi-finals of the reality TV singing competition It Takes Two in her native Australia. These days she runs a Whale Watch Expedition business, which has won her tourism awards, an Australian executive woman of the year award and a cover of Cosmopolitan magazine for being one of Australia's most successful young businesswomen.
