Meanwhile Meghan, 37, told Kate, 36, that she had felt snubbed.
The Duchesses spent Christmas Day together at the royal family's Sandringham House estate in Norfolk, England.
“Being under the same roof meant that they couldn’t avoid each other,” the source added.
A source previously told Us Magazine that Queen Elizabeth II "reached her limit with all the drama," adding, “She desperately wanted Meghan and Kate to make up and she got her wish!”
