Nearly two months after undergoing abdominal surgery, Catherine, the princess of Wales, appeared in an official photograph, released on Sunday by Kensington Palace to mark Mother’s Day in Britain.

Catherine, who posed with her three children, George, Charlotte and Louis, has not been seen in public since before she entered the hospital on Jan. 16, provoking a swirl of increasingly far-fetched rumors on social media about her condition.

The image of a smiling Catherine, surrounded by her family, will most likely quiet what had become an extraordinary distraction for the British royal family, which is also dealing with a cancer diagnosis for King Charles III. But it did not completely dispel the questions about the 42-year-old princess.

Kensington Palace, where Catherine and her husband, Prince William, have their offices, did not release any new details on her condition or convalescence. It said the photograph was taken by William this past week in Windsor, where the family lives in Adelaide Cottage, on the grounds of Windsor Castle.

In a post on social media accompanying the photograph, Catherine said, “Thank you for your kind wishes and continued support over the last two months. Wishing everyone a Happy Mother’s Day.”

Last week, a grainy paparazzi shot of Catherine, riding in a car driven by her mother, was posted on the American celebrity gossip site TMZ. British newspapers and broadcasters reported widely on the photograph, but did not publish it, honoring the palace’s appeal that she be allowed to recuperate in private.
