【watch Lady Chatterley's Daughter (2011)】

There's one relatively new royal family tradition that I can watch Lady Chatterley's Daughter (2011)definitely get behind. That's the birthday photos.

Each year, when the royal children celebrate their birthdays, Kensington Palace releases never-before-seen pictures taken by the Duchess of Cambridge. And they never fail to make us swoon over their cuteness.

This time it's Will and Kate's youngest child, Prince Louis -- and he's celebrating his first birthday.

The new official account for the Duke and Duchess of Sussex — AKA Harry and Meghan — posted a comment on the pic.
