NEW YORK — Actress Cybill Shepherd is penning a “tell it like it is” tome for HarperCollins, due out next spring.

The mid-six-figure deal, inked June 5, has Shepherd co-writing the book, “Cybill Disobedience,” with veteran magazine writer Jim Jerome (co-author of the best-selling Kathie Lee Gifford book, “I Can’t Believe I Said That”).

Acquiring editor for HarperCollins is exec editor David Hirshey, who said, “This will be a frank and outrageous book by one of our culture’s most indomitable icons of sex, beauty and comedy. Cybill will let her hair down about many of the larger-than-life characters who’ve drunk from her slipper — let’s just say we expect to be hearing from Elvis.”

The book, due in April 1999, will track Shepherd’s career from beauty queen to movie and TV star — a path that brought her in contact with the likes of Presley, Orson Welles, Martin Scorsese and her “Moonlighting” co-star Bruce Willis, who, said one insider, “will likely be in for a bad day.”

In addition to detailing “the truth behind her experiences on ‘Moonlighting’ and the outsize ego and erratic behavior of … Willis,” according to a Harper-Collins document concerning the book, “Cybill Disobedience” will discuss the “lose-lose trap faced by dynamic, beautiful women in Hollywood,” her relationships with Elvis and director Peter Bogdanovich, and the hardball world of high-level network TV politics.

HarperCollins is also clearly banking on Shepherd’s ability to reach women of a certain age group with her thoughts on aging and beauty.

“Cybill Shepherd speaks directly to women over 40 in America,” said Jane Friedman, CEO of HarperCollins. “She is a model of strength: outspoken, intelligent, funny and beautiful.”

Shepherd is managed by Judy Hofflund of Hofflund-Polone. The actress could not be reached for comment.
