Prince William seen leaving hospital where Kate Middleton is recovering from abdominal surgery

Prince William was spotted leaving the hospital where Kate Middleton is recovering from abdominal surgery.

Photographers captured the Prince of Wales driving away from the London Clinic in a black BMW Thursday morning with a stern look on his face.

William, 41, had a male passenger in the car as they left the private hospital in Central London’s famous medical district.

The sighting comes one day after Kensington Palace announced Middleton, 42, had undergone a “planned” operation Tuesday.

“The surgery was successful and it is expected that she will remain in hospital for ten to fourteen days, before returning home to continue her recovery,” read a statement posted to the couple’s Instagram Wednesday.

The palace revealed the Princess of Wales was “unlikely to return to public duties until after Easter.”

The statement said only “significant” updates on Middleton’s condition would be shared with the public, as she hopes to “maintain as much normality for her children as possible.”

She and William are parents to Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5.

“The Princess of Wales wishes to apologise to all those concerned for the fact that she has to postpone her upcoming engagements,” the statement concluded.

“She looks forward to reinstating as many as possible, as soon as possible.”

Though the details of Middleton’s surgery remain a mystery, Page Six reported it was not related to cancer.

An insider also told us that William would postpone some of his own engagements as he balances caring for his wife and parenting their kids.

Fans of the royal family were quick to comment well-wishes on Kensington Palace’s Instagram post.

“Wishing the Princess a speedy recovery,” one follower wrote, while another chimed in, “Sending all the healing energy her way.”

Later in the day, Buckingham Palace announced that a second member of the British royal family had to undergo a medical procedure: King Charles III.

His Royal Highness, 75, “sought treatment for an enlarged prostate,” according to a statement Wednesday.

“His Majesty’s condition is benign and he will attend hospital next week for a corrective procedure,” the palace added.

While Charles was out and about as recently as last weekend, Middleton has not been seen in public since Christmas.

At the time, she and her family coordinated in navy ensembles for mass at the Church of St. Mary Magdalene in Norfolk, England.
