Kate Middleton skipping the unveiling of a statue dedicated to the late Princess Diana at Kensington Palace on Thursday is “telling on so many levels,” according to family sources.

After the guest list was made smaller, it was revealed that Kate would not be attending the event dedicated to her husband Prince William’s late mother on Thursday. While it was expected that Kate would go to the event to help act as a peacemaker between William and his brother Prince Harry, one source told Page Six, “Catherine’s absence speaks volumes.”

“I think keeping the numbers down is a perfect ‘excuse’ for Catherine to stay away. William is fed up with the drama and Catherine doesn’t need to be dragged into this,” the insider said. “They are planning a private family visit with their children, and that private moment is far more important than the public rhetoric.”

“William is determined that the Sussex drama does not overshadow this important moment of remembrance to his much-missed mother and is keeping that as his focus,” the source continued.

Prince Charles, the ex-husband of Diana, will also be skipping the event due to the “old wounds” that could resurface.

“It brings back memories for him; happy, sad, regretful,” one insider said. “Since Diana’s death, he has felt it’s best to keep those memories to himself and leave his sons to it.”

Royal expert Camilla Towney told The Telegraph that there were concerns that Harry might be “outflanked” if William and Kate both showed up at the event. William and Harry have been feuding as of late, and it is unlikely that they will be reconciling at this event.

“It’s highly doubtful there will be a coming together of the brothers for anything more than the unveiling,” explained one source. “Harry can be petulant and defensive and is unlikely to apologize or even acknowledge any wrongdoing and William, who has seen the hurt caused by his brother ripple through the whole family, is not sanguine about how their relationship is changed for good.”

“The gulf between them is more than the 5,000 miles between London and California,” this insider added.
