The latest venture in their repertoire is their new book “Influence,” and Mary Kate and Ashley Olsen made a rare public appearance yesterday in Los Angeles.

The “Full House” hotties arrived at the Borders Books store in Westwood, California to a throng of fans, as well as a few PETA protesters.

Throughout the event, both Mary Kate and Ashley seemed to be in great spirits, joking and laughing with each other, and at one point they bent over cracking up together.

Fans of the Olsen twins lined up all day to get a glimpse of the famous duo, who were both dressed in their typical unique fashions.
