Ashley Olsen 'Influences' David Letterman

Fashion maven Ashley Olsen (in The Row) arrives at the Late Show with David Letterman to promote her new book Influence in New York City on Thursday.

The 22-year-old actress and her twin sister Mary-Kate had to deal with animal rights protesters during their New York book signing yesterday. Two representatives from PETA (People for the Ethical Treatment of Animals) wore “Trollsen Twins” masks, protesting their use of fur in their clothing collections. Signs at the event read: “Trollsens Fur Hags From Hell” and “Hairy Kate & Ashley”.
