The source also revealed to the Mail on Sunday that the Duchesses "don't really get on".
Harper's BAZAAR US reports that Meghan and Harry will be leaving their residence at Kensington Palace to move to the 10-bedroom Frogmore Cottage, on the grounds of Windsor Castle-where they Wednesday in May.
There are rumors swirling that Meghan Markle and Kate Middleton are feuding, and a source close to the royals is setting the record straight.
The Duke and Duchess of Sussex will move to live in your cottage in the grounds of Windsor castle. Former social worker, Doria, was the only member of Meghan's family to attend her wedding and held back tears as Prince Charles walked her daughter down the aisle. Sources claim that the two women do not get along.
While Kate was around 21 when she started dating William, Meghan was 35 at the time she met Harry, giving her many more years outside the royal bubble than her sister-in-law.
Melissa resigned from her job at Kensington Palace just six months after the American actress married into the Royal Family. "The property in Windsor is the next best thing".

But Sunday's action affected only the San Ysidro crossing, the busiest port of entry between the United States and Mexico. Brian Schatz, D-Hawaii, wrote that the "tear gas across the border against unarmed families is a new low".
But experts say there's nothing to worry about and the move is instead born of Meghan's desire to be far from the prying eyes of the paparazzi.
"The initial plan was for Harry and Meghan to move out of their cottage in the grounds of Kensington Palace and into one of the main apartments".
"It's pretty much confirmed Doria will be moving in and playing a hands on role as a grandma", he says. "Understanding the Palace way, the deference, the politics and the fact that there's a pecking order, is taking a while for Meghan to get her head around".
It might also have something to do with rumours Meghan might be having twins, as betting odds were suspended on the possibility over the weekend.
"Doria will be staying with them for quite long periods and they need a larger place", they added.
