Multiple sources told the newspaper that Kate, 36, was left in tears following a bridesmaid dress fitting for her 3-year-old daughter, Princess Charlotte, for Markle and Prince Harry's royal wedding.
“Kate had only just given birth to Prince Louis and was feeling quite emotional,” an insider told The Telegraph.
Kate welcomed her third child in April and Meghan, 37, and Harry, 34, tied the knot in Windsor, England, the next month.
This incident happened around the same time that Meghan had reportedly “upset” Queen Elizabeth II by asking to wear an emerald tiara instead of the one offered to her by Her Royal Highness.
Meghan recalled visiting Buckingham Palace to pick out her tiara in a recording for the royal wedding exhibit, calling the day a “surreal” experience.
While all of this was happening, royal reporter Robert Jobson said that Harry allegedly told the staff with a raised voice, “What Meghan wants, Meghan gets.” The comment allegedly prompted his grandmother to speak privately with Harry to “put him firmly in his place.”
The Telegraph goes on to note that the attitude “below stairs” has not been positive toward Meghan, with some staff saying they give the relationship “five years.” Reports of Meghan’s 5 a.m. wake-up calls and email “bombardments” of staff have raised some eyebrows, with some attributing the attitude to the former Suits star’s past Hollywood lifestyle.
The Telegraph also claims that one member of the royal family who is “completely taken” with Meghan is Prince Charles, with insiders saying it was Meghan’s influence that led Harry to have a closer bond with his father.
A royal source previously told ET, “Meghan and Kate have different interests and lead different lives,” adding that there “has been some tension,” between Prince William, Kate, Harry and Meghan.
"It's pretty obvious for everyone to see that Kate and Meghan are two completely different characters. They don't have a huge amount in common," royal correspondent, Katie Nicholl, told ET earlier this week. "I think Kate certainly, initially went out of her way to welcome Meghan into the family. ...She has tried to help show Meghan the ropes, but of course Kate's got her own family."
Nicholl added, "I don't actually think there's been any major falling out between the duchesses."
