Meghan Markle "embarrassed" Prince Harry after publicly divulging she was pregnant during Princess Eugenie's wedding day "in a huge social gaffe" which left the bride and her mother Sarah Ferguson furious, a new book has claimed.
The Duchess of Sussex, 38, is said to have revealed she was carrying her first child when celebrating Eugenie and Jack Brooksbank's nuptials with the rest of the Royal family on October 12, 2018.
But the former American actress' announcement didn't go down well with the Duke of Sussex, 35, according to investigative journalists Dylan Howard and Andy Tillett, in their explosive new book Royals At War.
"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," the pair wrote.
"This was a huge social gaffe, even if you were not a royal – stealing the limelight from Eugenie, who was furious, as was her mother, Sarah."
The authors claim the announcement left Harry, who is currently living in LA with his wife and son, feeling "embarrassed".
Meghan and Harry told the public they were expecting their first child on the eve of their royal tour of Australia and New Zealand on October 15, 2018.
At the time, some fans criticised the couple for making the announcement so close to Eugenie's wedding.
"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, a source previously told BAZAAR.com that Harry and Meghan did not break the news to their family at the wedding.
They claimed that the Queen and Prince Philip, Prince Charles and the Duchess of Cornwall, and Eugenie and Jack all knew about Meghan's pregnancy before the nuptials, but the big day was the first time they saw the couple in person to congratulate them.
They added that it was unclear whether the Duke and Duchess of Cambridge knew ahead of time.
A representative for Kensington Palace later said the Royal family were "delighted for the couple".
However, rumours of bad feeling went into overdrive when 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.
Kensington Palace officially revealed the pregnancy at 8.40am on October 15, 2018, on what was the Sarah Ferguson's 59th birthday.
And at the exact time of the announcement, Sarah posted a tweet thanking the designer of her dress for the outfit worn on her daughter's big day just days earlier.
She then posted three further messages saying how "proud" she was of her daughter and new son-in-law Jack - but made no mention of Harry and Meghan.
Eugenie's father, the Duke of York, who wished his ex-wife Sarah a "very happy day" on her birthday, also retweeted one of Sarah's tweets featuring Eugenie and Jack.
Prince Andrew also made no mention of the Duke and Duchess of Sussex's news.
