A royal expert said Kate was no longer "the sister Harry never had."
Royal family expert Duncan Lacombe made the remarks while talking about Kate's upcoming 40th birthday. Until then, Lacombe said, Harry would not "contribute" to Kate's birthday at any party.
However, the royal expert, stressing the rift between William and Harry, said "those days have passed a long time".
Lacombe told OK! Magazine: "It would be interesting to see what Harry and Meghan sent Kate. That's the problem, and as the disagreements continue, and as the war between the boys seems to show no signs of ending, days like Kate's 40th birthday milestone are immediately comparable to the past. ”
As Harry said, Kate was the sister he had never had, and now it's clearly not anymore. There was a time when Harry would play an important role in any celebration and bring any fun to the couple, but those days are long gone. ”
Kate's birthday isn't the only family birthday this month, with her mum Carol celebrating her big day on Jan. 31.
