Kate Middleton will not attend Easter service because of cancer diagnosis, chemotherapy treatment

“William and I have been doing everything we can to process and manage this privately for the sake of our young family,” Middleton, who wore a striped sweater and jeans, said somberly.

The princess noted that she and her husband, Prince William, needed “time to explain everything” to their kids — Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5 — in an “appropriate” manner before sharing the news with the world.

Middleton’s biggest concern was to “reassure” her children that she was “going to be OK.”

“As I have said to them, I am well and getting stronger every day by focusing on the things that will help me heal, in my mind, body and spirits,” she explained.

“Having William by my side is a great source of comfort and reassurance too,” she said, putting to rest unfounded rumors that their marriage was on the rocks.

“As is the love, support and kindness that has been shown by so many of you. It means so much to us both.”

Middleton, who described the last couple of months as “incredibly tough,” wrapped up her message by asking for “some time, space and privacy” as she completes her treatment.

She concluded the video by encouraging those battling cancer to “not lose faith or hope” and know they “are not alone.”

Just one hour after the emotional announcement, a Buckingham Palace spokesperson told Page Six that King Charles III — who is also battling cancer — is “so proud of Catherine for her courage in speaking as she did.”

They noted that the monarch has “remained in the closest contact with his beloved daughter-in-law throughout the past weeks” and will continue to support their family during this “difficult time.”
