The Duke of Sussex, 35, felt the Queen's granddaughter, 30, had 'had always been more than a cousin' and they were 'also the closest of friends', according to Omid Scobie and Carolyn Durant, who wrote book Finding Freedom, released today. .

However the decision taken by Prince Harry and Meghan to share the news of their pregnancy at the Princess' wedding 'did not go down particularly well', according to the authors.

The Duke of Sussex, 35, felt the Queen's granddaughter, 30, had 'had always been more than a cousin' and they were 'also the closest of friends' (pictured: Harry with Eugenie and Princess Beatrice in 2015 on Trooping the Colour) .

The Duke and Duchess of Sussex told close family members the news at the nuptials because it was the last time they saw senior royals before jetting off to Australia for the start of their royal tour. .

According to the book, Prince Harry and Princess Eugenie had always had a strong bond.

The authors write: 'Out of all the queen's grandchildren, Princess Eugenie and Prince Harry have one of the most natural connections.

The book reveals Eugenie was furious about the fact Meghan and Harry 'stole the limelight' at her wedding by announcing the Duchess of Sussex was pregnant .

The Duchess of Sussex, 38, is said to have revealed she was carrying little Archie, now one, when celebrating Eugenie and Jack Brooksbank's nuptials (pictured above) with the rest of the Royal family on 12 October 2018?

Meanwhile they also detailed how Prince Harry even confided in his cousin early on in his relationship with Meghan.

The authors wrote: 'Harry had always confided in his cousin when it came to the women in his life.

The pair wrote: 'Meghan put her foot in it when she decided that it would be the ideal moment to announce that she and Harry were expecting their first child.'

'If Harry and Meghan did actually tell the royal family about their baby at Eugenie’s wedding on Friday, that’s pretty shady,' one person wrote, while another added: 'Thunder stealer.' 

However, rumours of bad feeling went into overdrive when Princess Eugenie's mother tweeted a picture of her royal wedding outfit at the exact moment the Duke and Duchess of Sussex announced they were having a baby
