There's a Royal Reason Why Guests Are Eating 7-Year-Old Cake at Prince Louis's Christening

Between the guest list, the special date, and even the dessert, every detail of Prince Louis's royal christening has been planned to perfection. Similar to big brother Prince George's, Prince Louis's christening will take place in the Chapel Royal at St. James's Palace in London on Monday, July 9. While there will be some new family members in attendance for the special occasion, the royal family will also bring a slice of history to the post-service celebrations.

According to Kensington Palace, guests will enjoy tea and cake at Clarence House. The "christening cake" is a tier of Prince William and Kate Middleton's wedding cake from 2011. We know what you're thinking: cake from 2011?! But the eight-tier cake was "made from 17 individual fruit cakes" and is "preserved" for a christening.

After news of the aged wedding cake hit the internet, Twitter users immediately chimed in on the situation — some explaining the tradition, and others utterly confused. "It's a British custom. Fruit cake laced with enough brandy lasts until the end of the world. And will tasted just as good/bad as originally," one user wrote. Another added, "It's a strange tradition we have. The top tier of the wedding cake is kept aside for any future christenings. Seven years is just when the parents were married — it would have tasted a bit fresher for the previous two."

The things we do in the name of tradition!
