Princess Catherine's carol concert is now just hours away, with many attendees no doubt already getting excited for the event. While many people have helped shape tonight's carol service into what it will be, this also includes one very famous face.

In a video shared yesterday ahead of the carol concert, Mary Berry - famous baker and friend of Catherine's - was seen helping to make wreaths for display in Westminster Abbey, where the service will be held. Mary made the wreath at RHS Wisley Garden with ambassadors and Friends of the RHS, including Angelica Bell, Tom Allen, Arit Anderson and Simon Lycett.

The appearance of Mary was no doubt a delight for fans, especially as she has a close bond with Catherine.

The pair have been in each other's company many times, including when The Prince and Princess of Wales made an appearance on the BBC One show A Berry Royal Christmas.

This saw Kate reveal that she often used Mary's cookbooks to make food with her children, including Mary's pizza recipe.

The princess also revealed to Mary that one of Prince Louis' first words was Mary as he would look at the cookbooks in the family's kitchen.

She told Mary: "One of [Prince] Louis' first words was Mary, because right at his height are all my cooking books in the kitchen bookshelf."

Although Princess Catherine's carol concert is being held tonight, it will not be available to watch on TV until Christmas Eve.

Catherine will be joined by her nearest and dearest at the event, including her husband Prince William and their three children Prince George, 12, Princess Charlotte, 10, and Prince Louis, seven.

Other members of the Royal Family are also expected to attend, including Zara Tindall.
