Just months after marrying Keith Urban, Nicole Kidman has come under fire in an unauthorised biography depicting the actress as too self-obsessed to give herself to a husband.

The Hollywood heavyweight has been left feeling manipulated by the book's author, US film critic David Thomson, because she was unaware the project would be published in the form of an explosive biography.

Her agent said: "Nicole has never met David Thomson - she has only spoken to him briefly on the phone about her acting processes and various films."

She agreed to the interview only because she was under the impression he was writing a series of film essays.

However, the book called Nicole Kidman, which hit US shelves this week, paints the actress as a power-hungry fame seeker who used her 10-year marriage to Tom Cruise to hit the Hollywood big time.

The Oscar winner is yet to announce legal action against Thomson, who, in his previous book The Whole Equation: A History of Hollywood strangely confessed to having a deep crush on the star.
