The bridal gown hasn't even been finalized yet, but it would appear Prince Harry and Meghan Markle have already settled on their perfect wedding cake.

The royal nuptials won't take place until May 2018, but already royal watchers are speculating the finer details of the reception as they await new developments beyond what we already know about the big day—namely that the ceremony will take place at St. George's Chapel outside Windsor Castle.

Although Prince Harry and Meghan Markle have kept mum about their wedding preparations thus far, sources close to the happy couple reveal they're opting for less traditional fare when it comes to their wedding cake.

The dynamic duo, who announced their engagement on Nov. 27, want a cake made entirely from bananas, an insider tells The Telegraph. The reason is actually quite charming.

In addition to the prince's lifelong love for "anything with banana," the fruit has played an even sweeter role in their whirlwind courtship.

Only a few hours after their romance was (finally!) confirmed in October 2016 after months of endless speculation, the former Suits actress posted a cryptic (but incredibly adorable) image of two cuddling bananas on her Instagram. She captioned the photo: "Sleep tight xx."

The now-famous banana post, which sent royal watchers into a frenzy one year ago, now carries a special new meaning as the pair prepare to celebrate their big day with a banana cake. The unconventional dessert choice is a first for a royal wedding: British tradition calls for fruit cake as the top tier because it lasts long enough to be served at the christening of the couple's first child, should they have any.

"It's always been a tradition and that's why the cake [is often] fruit cake, because after 30 months it's even more delicious," Fiona Cairns, who created Prince William and the Duchess of Cambridge's eight-tier wedding cake, recently told Hello! magazine.

Either way, we're going positively bananas for Harry and Markle's unconventional dessert choice.
