Meghan Markle dropped a subtle hint about being in love by sharing a picture of a cute banana couple snuggling together on her Instagram account thirteen months ago.

Now the fruit is all set to play a major role at the Royal wedding, as the couple have decided to go for a banana-flavoured cake for their big day.

The Daily Telegraph quoted a source close to the couple as saying: "This will be the first royal wedding cake made from bananas."

The Instagram picture, which was accompanied by the caption "Sleep tight xx.", sent fans into a flurry of excitement as they immediately started making connections with Prince Harry.

And they weren't wrong. Apparently, Prince Harry loves bananas.

Former royal chef Darren McGrady had previously revealed in an interview with Hello! magazine that Prince Harry and Prince William both "loved banana flan, anything with banana really, banana ice cream".

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) 🍌👍🏽

If the couple's wish is granted and they have a banana cake at the wedding, it will be a break from tradition. The top tier of all royal wedding cakes has always been a fruit cake, which is later served at the christening of the couple's first child.

Before this, the Duke and Duchess of Cambridge had also broken from convention and served a cake made of chocolate biscuits for their reception at Buckingham Palace, along with a traditional eight-tiered cake.

Ever since the engagement announcement, fans have continued to speculate about wedding arrangements. However, the couple have kept most of it under wraps.

Markle was previously married to Hollywood producer Trevor Engelson. Ninaki Priddy, the Suits actor's maid of honour from her first wedding, has recently slammed the royal bride-to-be saying she completely changed after gaining fame from the TV show.

"There's Meghan before fame and Meghan after fame. After three seasons of Suits, she called me to say the marriage was over. Maybe she had started to change before then, but I was refusing to see it. The tone of her voice, her mannerisms, the way she laughed didn't seem real to me anymore," said Priddy to the Daily Mail.

"I think it's a very fanciful dream to believe that you just walk into a Prince Charming," added Priddy. "I know the Royal Family was something she found fascinating. She had one of Princess Diana's books [Diana: Her True Story] on her bookshelf, and even when she was with Trevor she told me she wanted to go and stay in London for at least a month."

The royal wedding will take place in May next year at St George's Chapel, Windsor Castle.
