Prince Harry and Meghan Markle's wedding cake will be unique.

Last week, the "Suits" star and Prince Harry announced their engagement. The couple also shared some details about their upcoming wedding in St. George's Chapel in Windsor Castle in May 2018. Now more details about the next royal wedding have been revealed.

An insider told The Telegraph that the couple will have a wedding cake made from banana during their reception. "This will be the first royal wedding cake made from banana," the source said.

The source added that Prince Harry is fond of the fruit and loves "anything with banana." In fact, Darren McGrady, former royal chef, used to make caramel and banana cake for him.

In a separate interview with Hello! magazine, McGrady revealed that Prince Harry's older brother, Prince William, loves bananas too. The two princes enjoy anything made from bananas, including "banana flan, anything with banana really, banana ice cream."

The "Horrible Bosses" star has the same fondness for bananas. In 2016, Markle shared a photo of two bananas spooning on Instagram. "Sleep tight xx (Update: Thanks so much to those who shared the photo cred :) I didn't know, and I love it! Credit where credit is due: I'm bananas for this @percxption) ," she wrote in the caption.

The publication noted that Prince Harry and Markle's choice to go with banana cake instead of the typical fruit cake is similar to Prince William and Kate Middleton's choice. In addition, award-winning wedding cake designer Rosalind Miller observed that more couples prefer flavored sponges than traditional fruit cakes. "People are becoming more aware of different flavors," she said.

"A traditional wedding cake is a rich fruit cake, like a Christmas cake, where all the cake is soaked in alcohol first," Miller explained. "But with Meghan being American, they are more used to having sponge cakes. We find that in actual fact, most couples that come to us also want sponge cakes these days. The traditional rich fruit cake is not very popular now."

Although Prince Harry and Markle have shared some details of their upcoming wedding, the couple remains tight-lipped about their preparation. A source close to the royal family, however, revealed that the next royal wedding will be televised.

Kensington Palace will reportedly allow cameras in St. George Chapel to broadcast the ceremony. Millions are expected to watch the live stream. In 2011, 23 million Americans and 27 million Britons tuned in to witness the Duke and Duchess of Cambridge's royal wedding.
