Through their social media, the British royal family celebrated Kate Middleton's 43rd birthday, highlighting her strength and courage.

Middleton made a subtle return to royal duties towards the latter half of 2024, making surprise appearances alongside Prince William and attending royal events like the annual Trooping the Colour celebration or her Christmas Carol concert. The consistency, however, wasn't there—and it's very intentional.

Princess Kate is celebrating her 43rd birthday. Her husband, Prince William, honored the "most incredible wife and mother" in a new post.

In the photo, Middleton traded sleek coats and heels for something more casual. She wore a dark blazer jacket rolled and cuffed at the sleeves with a crisp white button-up top. Completing the outfit was a checked plaid printed scarf worn around the neck and fitted dark jeans with light whiskering at the hips.
