Kate Middleton and Prince William’s latest Christmas card photo (Spot the Unique Element)

Over the weekend, Prince William and Kate, both 41, unveiled a laid-back family photo featuring the children in coordinated white shirts, set to grace the front of their festive card this year.

However, the Christmas portrait of the Prince and Princess of Wales with their three children has sparked discussions about a potential Photoshop error. The monochrome image captures the royal couple smiling alongside their sons Prince George, ten, Prince Louis, five, and Princess Charlotte, eight, the latter seated in a chair at the forefront of the group, with Louis’ hand resting on the arm.
