"Meghan had her heart set on this tiara with emeralds and Prince Harry hit the roof when they were told it was impossible for her to wear it", the source said.
Another article in the Daily Telegraph dished on Kate being reduced to tears during a dress fitting for Princess Charlotte before Meghan's wedding, allegedly over the way Meghan acted leading up to the wedding, which upset Kate.
Can't get enough of PEOPLE's Royals coverage?
One of William's friends told the MoS: "The problem is that the Cambridges felt things had moved very quickly between Harry and Meghan".
Prince Harry and Meghan Markle
Since then, Kate, 36, and Meghan, 37, have made several joint appearances as part of the Royal Fab Four - and even attended Wimbledon for solo outing without their husbands over the summer.
"Absolutely!" Kate immediately responded, according to a video shared by Harry_Meghan_Updates on Instagram.
She said: "My biggest piece of advice would be to take some time and don't be in a hurry to do anything".
And while the royal family doesn't decorate the trees at Buckingham themselves, the youngest members of the Windsor clan (a.k.a. Prince George, Prince Charlotte, and Prince Louis) won't be missing out on the opportunity to bedazzle a fresh fir with ornaments and tinsel. "It'll be really special".
Kensington Palace also recently announced Markle and Prince Harry would move out and relocate to Frogmore Cottage in Windsor, England, as they prepare for the birth of their first child this coming spring.
Those who know the princes say that there was always a chance that they would not want to live in each other's backyards.
But Harry wasn't having a bar of it telling his grandmother - her Majesty - that "what Meghan wants, Meghan gets".
Rubbing salt to the wound, this latest drama stems from the highly publicised rumoured tiff between Duchess Kate and Meghan and royal household shakeup with the Sussexes moving out of Kensington Palace.
According to People, the two women will spend Christmas together amid all the feud rumors.
