Performers always seem the ideal people to pass on words of wisdom about how to live a fulfilling life.

So no wonder Jessica Alba was mobbed by fans as she signed copies of her tome The Honest Life in Bethesda, Maryland on Friday.

The Fantastic Four favourite looked like she was raring to go after she pulled up at the venue ahead of her autograph session.

The 32-year-old Sin City actress looked in fine figure in a patterned orange dress and stacked heels.

Jessica has claimed the reason she wrote the money-spinning book was because she was frustrated by the lack of trustworthy information available for parents on how to live healthier and cleaner.
