Meghan Markle aspires to be 'Princess Diana 2.0' according to a new book which also claims she was deeply affected by her death.
The Royal bride-to-be also dumped first husband Trevor Engleson by post, Andrew Morton's biography - Meghan: A Hollywood Princess - claims.
She ended their marriage 'totally out of the blue', sending their rings in the mail after taking walking out with a £360 blender from their West Hollywood home before moving to Toronto
The book - which is being serialised by The Sun on Sunday - features a former friend's claims that the Suits star is a social climber who left Engleson in a 'cold fury' that still surfaces five years later.
Describing Meghan as 'controlling' and 'fastidious' the biography says she grew tired of her husband's 'scattered approach to life' while she starred in the legal drama.
He was not the only one experiencing the Meghan chill,' Morton writes. 'She no longer had the time for friends she had known for years.'
A friend says the actress left the film producer feeling like something stuck on the bottom of her shoe.
Engelson had found his then girlfriend a role in 9/11 melodrama Remember Me, which starred Robert Pattinson, in 2009.
Meghan's fascination with Diana - whose biography was also written by Merton - caused her and friends to cry as they watched the funeral on television in 1997.
The author also reveals how Harry's future wife thought Donald Trump was 'super creepy' when she met him on the US Deal or No Deal set.
The future US president was appearing on the show as a guest in a cross-promotion push for The Apprentice.
He handed 'briefcase girls' on the set business cards and invited them to play golf at one of his courses.
One former classmate described Meghan as a 'party animal' during her time at Northwestern University in Chicago where she read theatre and international studies.
Her political ambitions led her to take an internship at the US embassy in Argentina after uncle Mick Markle pulled strings.
When Meghan's car was attacked by protesters in South America during a visit with finance secretary Paul O'Neill, her father, Tom, helped her land a TV role.
Tom Markle was so besotted when his daughter was was born on August 4, 1981, that he and her mother Doria dubbed her 'Flower'.
It wasn't just his life that changed with her arrival, but the lifer of Meghan's older half-brother Tom Jr, 51.
Andrew Morton's biography reveals how Tom told Tom Jr that if he wanted to smoke weed he would have to do so at home.
But the son says his father announced that he would change Meghan upstairs while he and his friends were smoking one day.
Tom re-appeared carrying a full nappy and ate the contents with a spoon in front of the boys, who fled in horror.
The prankster later revealed he'd stuffed a fresh nappy with chocolate pudding to stop them smoking near Meghan.
Tom Jr says his father was 'blown away' by Meghan's birth and was 'more in love with her than with anyone else in the world'.
Meghan's parents met after Tom's marriage to first wife Roslyn broke down and he got to know trainee make-up artist Doria on the set of General Hospital.
The couple began to argue when workaholic Tom spent up to 90 hours a week on set.
He believed Meghan was his good luck charm when he and colleague on General Hospital won a Daytime Emmy for Outstanding Achievement in Design Excellence in 1982.
But it took a toll on Doria, who also had to suffer through people thinking she was the house's nanny due to Meghan's light skin.
Family friends say Tom constantly criticised Doria, with the pair splitting up when Meghan was two, leaving her father with weekend custody.
The parents enrolled Meghan in the exclusive Little Red School House when she was two years old in 1983.
The kindergarten was favoured by LA’s showbusiness elite and was attended at the same time by Scarlett Johansson.
Tom became lighting director on Married . . . With Children when a 10-year-old Meghan sat watching on the studio floor.
Meghan said growing up around the raunchy comedy was perverse, citing how she saw people such as former porn star Traci Lords.
It was about this time that Tom won the California State Lottery, taking $750,000 (£530,000), a win he kept secret due to outstanding divorce matters.
But the friend he sent to pick up his winnings swindled him out of most of his fortune and Tom was bankrupt in three years.
Meghan became skilled at keeping her emotions in check after mediating between her father and mother.
The young actress' big break came in 2003 when she landed a role in A Lot Like Love with Ashton Kutcher.
Then in 2011 she was cast in Suita, which would become the highest-rated US TV show for viewers aged 18 to 49.
As her celebrity profile increased, Meghan started charging upwards of $20,000 (£14,250) for appearances.
Harry has impressed Elizabeth II representing her on official duties and his brother has also inspired with his 'star quality'.
