Kate did admit to manipulating the photo, issuing an apology in a statement. She confessed "occasionally experiment with editing" like "many amateur photographers" on Twitter, now known as X.

"This is in an unprecedented time for the Wales family as the princess continues her recovery," the source stated.

Last month, the family faced adversity when Kate, 42, disclosed that she had commenced chemotherapy for cancer during its initial stages.

"The family were cognizant of the fact that they have asked for privacy during the princess' recovery, however, on balance, they wanted to share the image on their social media channels as a way to thank those who have sent birthday wishes," the source claimed.
