It seems that the ongoing rift between Prince William and Prince Harry is having a significant impact on Kate Middleton, despite her attempts to appear unfazed by the drama.
Before Harry's departure from senior royal duties following his marriage to Meghan Markle, he would often accompany Kate and William at public events, showcasing the closeness between them.
Harry even described the mother-of-three as the "sister he'd never had and always wanted" in his memoir, Spare.
Andersen has suggested that Kate's relationship with Harry has always been special, and the rift between the brothers is weighing heavily on her.
"When it comes to acting the part of someone who seems totally unfazed by all the drama swirling around her, Kate really delivers the most convincing performance," he said. "She never lets her guard down the way the other three do."
The royal biographer also claimed that Kate must have played a part in convincing William to make an appearance with Harry and Meghan outside Kensington Palace after Queen Elizabeth’s passing, despite William's reluctance to make amends with his brother.
Whenever the four are together, Andersen said, "I don't think we have seen anything but forced smiles on all their faces."
