The Duchess will celebrate her landmark birthday next Sunday.
But the celebrations for Kate’s 40th birthday will be muted – like her Christmas – due to the Covid risk, The Mail on Sunday understands.
It is not expected that the Duchess of Cambridge will throw a large party. Instead, she will host an intimate affair with her family and closest friends.
Kensington Palace will celebrate the historic occasion with a brand new photo of the Duchess. The Duchess is also a talented photographer.

The Duchess will likely have a smaller party with close family members and friends, instead of throwing a huge event.
