Prince William made a visit to Catherine Masters, who is living in a care home and assured her that his grandmother would put on another outfit for this years cards.
Once the 109 year got over her shock, the pair of them sat and had a cup of tea.
Catherine Masters explained to Prince William that the Queen needed to choose some more clothes for future pictures.
The two are said to have chatted about everything from the recent badminton horse trials which are held in the UK every year and Prince Williams cooking skills were also up for discussion.
The Great Grandmother has also been given an invitation to this summers garden party which will be held at Buckingham Palace in July.
Wendy Mead, who is a senior nurse manager at the care home said:
We received a call and within five minutes, Prince William had arrived,"
"It was a total shock, and Catherine was speechless. Prince William came in and she asked if he was real. She squeezed his hand to check."
"He told her he liked making shepherd’s pie and said he used a masher to mash the potatoes, but she told him he was doing it wrong – he should use a fork to fluff the potatoes,"
