The Andrew Morton book also claims she was dating another Aussie actor when she began seeing Cruise on the set of a blockbuster film, and that she sometimes took days to phone home to ask about their two children.

The sensational book, which has sparked a $100 million legal threat from the Church of Scientology, purports to provide insights into the couple's early relationship as well as what caused them to divorce in 2001.

Its release in the US last week coincided with the leaking on to the Internet of several creepy Scientology recruitment videos featuring Cruise.

Morton's book, which will not be published in Australia or the UK because of the legal threat and more stringent defamation laws, charts the Cruise-Kidman relationship from its fairy tale beginning to the bitter end.

"Even though the couple had two nannies on-call 24 hours a day, Tom was very much a hands-on dad," Morton writes.

"When Nicole was away filming or, increasingly, flying to Sydney to spend time with her parents and sister, it could be days before she would phone to see how Isabella and Connor were coping.

"Those who saw the family close up concluded that Tom was much more comfortable and enthusiastic as a parent. The actor was in constant - and controlling - touch with the youngsters and their nannies no matter how busy he was."

Morton says that during their 10-year marriage, Kidman often behaved like a spoilt "diva".

"If the jet wasn't stocked with Beluga caviar and all the trimmings she appeared deeply irritated, exhibiting a jaded petulance,'' he wrote.

"Nicole often seemed bored or disenchanted with her life as a Hollywood star, expecting a luxurious lifestyle as her birthright.

"She had no sense of wonderment about the world. So many wonderful things happened to her, but she had an enduring sense of boredom - like some 1920s flapper. She never delighted in anything."

The book also claims Cruise and Kidman were both attached when they began their relationship.
She was allegedly still in a relationship with Aussie actor Marcus Graham and Cruise had recently separated from his wife, Mimi Rogers.
