Prince Harry and Meghan Markle are going to break royal tradition with their choice of wedding cake...

We still don't know the exact date of Prince Harry and Meghan Markle's royal wedding, but there's one detail we do know...

The wedding cake will be bananas — literally.

While royal chefs usually serve a booze-soaked fruitcake for the royal's nuptials, Harry and Meghan have reportedly requested a banana cake.

And the reason why has a romantic twist.

Not only does the 33-year-old prince reportedly love anything banana-flavored, but the fruit has also played a big role in their relationship.

Just hours after People confirmed their relationship, the 'Suits' actress posted a cryptic image of two cuddling bananas on her Instagram.

“This will be the first royal wedding cake made from bananas,” a source told the Daily Telegraph.

Traditionally, the royal's wedding cake is a fruit cake, because it lasts long enough to be served at the christening of the couple’s first child.
