Princess of Wales appears in first photo since surgery amid wild speculation of her whereabouts. "Thank you for your kind wishes and continued support over the last two months," Kate said on social media.

Kate, 42, underwent surgery Jan. 16 and her condition and the reason for the surgery have not been revealed. The royal family has been under more scrutiny than usual in recent weeks, because both Kate and King Charles III can't carry out their usual public duties because of health problems. Royal officials say Charles is undergoing treatment for an unspecified form of cancer.
