Olsen twins to write fashion book

Actresses Mary-Kate and Ashley Olsen are adding authors to their list of talents - the twins are releasing a coffee table book about their fashion inspirations.

The 21-year-old siblings are penning a text entitled Influence, which will detail their favourite style icons and the people behind them, including shoe designer Christian Louboutin, actress Lauren Hutton, photographer Terry Richardson and writer Bob Colacello.
