The Prince and Princess of Wales will miss the royal gathering for the annual Easter Sunday service in Windsor, HELLO! understands.
Prince William and Kate will instead spend the Bank Holiday weekend at their country abode, Anmer Hall, in Norfolk, with their three children.
The Waleses have taken a break from their public duties in recent weeks while Prince George, 11, Princess Charlotte, nine, and Prince Louis, six, are on their school holidays from Lambrook.
It will be the second year in a row that William and Kate have missed the church service. Last year, Easter Sunday fell just days after the Princess announced her cancer diagnosis in a personal video.

Recent appearances
Earlier this week, Kensington Palace shared a video of the Princess of Wales taking a walk around the Lake District with a group of Scouts.
The footage, which was filmed in March, saw Kate sporting a casual outdoors look with a baker boy hat as she spoke about her close connection to nature.
Speaking to Chief Scout Dwayne Fields, the Princess: "I find it a very spiritual and very intense emotional reconnection I suppose, these environments.
"Not everyone has that same relationship perhaps with nature, but it is so therefore meaningful for me as a place to balance and find a sort of sense of peace and reconnection in what is otherwise a very busy world."
Kate, who is now in remission, is making a gradual return to her public duties. Her last engagement was on 17 March when she attended the St Patrick's Day parade with the Irish Guards at Wellington Barracks in London.
