Kate Middleton is not relying on support from Prince Harry and Meghan Markle following her cancer diagnosis, a royal expert has claimed.

The Princess of Wales, 42, revealed on Friday that she has been undergoing chemotherapy treatment after doctors discovered the cancer during her planned abdominal surgery.

And according to royal author Sally Bedell Smith, Middleton has enough support from within the royal circle that she “doesn’t need” to hear from her brother-in-law and his wife.

“Kate doesn’t need Harry and Meghan to console her,” Smith told the New York Times. “She has her parents and a sister, and she’s very close to King Charles.”

Following the mom of three’s announcement Friday, Harry and Meghan said they hope for privacy for the Princess as she undergoes treatment.

“We wish health and healing for Kate and the family, and hope they are able to do so privately and in peace,” the Duke and Duchess of Sus𝓈ℯ𝓍 said in a statement.

It’s understood that the pair, who quit royal life in 2020 and hightailed it across the pond, made contact with the Prince and Princess of Wales “privately” following Middleton’s announcement.

Still, it appears as though the Waleses made a conscious effort to keep the Sus𝓈ℯ𝓍es out of the loop regarding their health woes, sources told The Post.

Harry and Meghan were reportedly blindsided, learning of Middleton’s health struggle on the very day the tragic news broke to the world.

“They had no idea, and only learned of the news around the same time the rest of the world found out,” an insider disclosed.

“This goes to show the irreparable damage they have caused,” the source said. “The trust has been broken and the royal family is OK distancing themselves from them.”

In a video message shared on social media Friday, Middleton revealed her ailing condition following weeks of intense speculation.
