Her father, Thomas Markle, has continued to give explosive interviews about his strained relationship with his daughter and the royal family.
“It was very wearing on her. It’s her private life,” says a source.
The newlyweds have been spending time with Harry’s father, Prince Charles, who hosted them at the remote Castle of Mey in Scotland this summer. Meghan is also focusing on the tasks ahead, including her charity work and her first major international tour Down Under alongside Harry next month.
“The tour is going to be her chance to shine,” says Ingrid Seward, author of the recent biography of the Queen and Prince Philip, My Husband and I. “She knows she’ll be center stage, and everyone is going to want to meet her.
“It is her biggest part yet. I’m absolutely confident she will be very, very good.”
