Kate Middleton debuts blond hair in joint appearance with Prince William

Kate Middleton debuted long, blond hair while stepping out for a joint appearance with her husband, Prince William.

The Princess of Wales, who battled cancer last year, showed off lighter locks on Thursday at the Natural History Museum’s newly renovated gardens in London.

The natural brunette opted for a dark blond shade with a slightly off-center part, complete with honey highlights.

Middleton maintained her signature tailored fashion style, changing up her beauty look with extra-long tresses that reached the middle of her back, styled in loose waves.

The Duchess of Cambridge looked sleek in a white collared shirt tucked into fitted dark teal slacks, cinched by a black belt.

She wore a pewter tweed sport coat and completed her ensemble with brown suede flats and simple jewelry.

The 43-year-old smiled as she posed for pictures alongside William, also 43, who paired a black suit with an unbuttoned baby blue button-down.

The outing marked their first as a royal couple since the summer break.

Middleton’s new hair is a departure from the rich chestnut color she was rocking at the Wimbledon Championships in mid-July.

The mother of three — who shares Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7, with the Prince of Wales — has been easing back into her royal routine after going into remission in January.

She has said it will take time to get back to her regular schedule after fighting “an incredibly tough battle” with the “complex, scary and unpredictable” disease.

Middleton — who married William in April 2011 — revealed in March 2024 that she had been diagnosed with cancer, not specifying the type.

At the time, she explained that she had undergone “major abdominal surgery” for an unspecified “condition” that she thought was “non-cancerous.” However, the operation led to the diagnosis.

She announced in September 2024 that she had completed her chemotherapy treatments.
