New photo of Prince William with his children released to mark his birthday [Video]

A new photo of William, the Prince of Wales, and his three children was released Friday by Kensington Palace to celebrate the future British monarch‘s 42nd birthday.

The image, published on the joint social media channels of Prince William and his wife Catherine, the Princess of Wales, included the message: “Happy birthday Papa, we all love you so much!” It was signed “Cx,” an abbreviation for the Princess of Wales, who’s often referred to as Princess Kate.

The palace said the image was taken by Kate in Norfolk, southeast England, in May. Kate has been undergoing treatment for an unspecified form of cancer. She made her first public appearance last weekend, at a parade to mark King Charles III’s birthday, since announcing her diagnosis in late March.
