Actress Katie Holmes' life has reportedly been the inspiration for author Lori Culwell's new book Hollywood Car Wash, after critics pointed out the uncanny similarities to the novel's lead character. Culwell's book portrays the life of a young actress who finds herself thrust into the limelight when she begins dating a big Hollywood star - an apparent mirroring of the Batman Begins star's own life, in which she is married to Tom Cruise. Culwell says, "It's all based on real stories and the main character is based on a person that is never, ever going to talk to me again." But Holmes's representative insists, "Never heard of this book, never read it and doesn't know the author."
