About Jenny McCarthy
Jenny McCarthy's honesty, humility and humor have enabled her to transcend the boundaries of her roles as comedian, actress, host, best-selling author and influential activist in the world of healing and preventing autism. When she first made her own experience with her son Evan's diagnosis and subsequent recovery from autism, her unique ability to articulate the unspoken words of thousands of mothers and fathers across the world was recognized immediately, and she is now fielding hundreds of requests per week for interviews, speaking engagements and public appearances nationwide.
A highly-regarded NY Times best-selling author, McCarthy's books include the bestsellers "Belly Laughs, Baby Laughs, Life Laughs," "Louder Than Words: A Mother's Journey in Healing Autism" and "Mother Warriors: A Nation of Parents Healing Autism Against All Odds." "Healing and Preventing Autism," co-written with Dr. Jerry Kartzinel, was published in April 2009. Her new book, "Love, Lust and Faking It: The Naked Truth About Sex, Lies and True Romance," hit stores in September, also landing on the NY Times Bestseller List.
