Prince William and Kate Middleton may have taken Prince Louis along with them to last week’s Christmas lunch with Queen Elizabeth II in Buckingham Palace.

Initial reports claimed that the youngest child of the Duke and Duchess of Cambridge skipped the gathering because he was still too young to attend. However, royal fans are now convinced that Prince Louis was actually there.

In the closeup photo of Prince William and Middleton in their car, a baby’s car seat is also visible. The seat is positioned right behind the royal couple. A seatbelt also appears around the car seat, which suggests that it may have been used to keep the baby’s car seat in place.

The theory about Prince Louis’ attendance was somehow proven after the family’s nanny, Maria Barrallo, was seen sitting in the middle row. Prince George and Princess Charlotte sat behind on the rear row.

“I know many people are saying Prince Louis wasn’t there but I think he was. In pictures you can see a car seat behind Kate and also there is a picture (can u find it) where Nanny Maria was looking over to the car seat,” one fan tweeted.

Other young family members who attended the Christmas lunch in Sandringham were Lady Louise Windsor, Isla Phillips and Mia Tindall.

In related news, the members of the royal family also made headlines this week after the hardest-working individual from the British clan was named. An analysis of the Court Circular by the Sunday Telegraph revealed that Princess Anne worked the most days compared to any other royal so far in 2018 with over 180 engagements.

Princess Anne was declared as the most hardworking royal for this year. She is currently involved with over 300 charities, organizations and military regiments. She also frequently conducts official visits. Princess Anne is especially close with the Carers Trust, a charity that provides support for those caring for chronically ill and disabled family members and friends. The only daughter of Queen Elizabeth II launched Carers Trust in 1991.

Prince Edward lagged closely behind his older sister with 170 working days. Third on the list is Prince Charles, who worked 160 days.
