This has absolutely nothing to do with royalty it seems. Popular YouTube channel Bad Lip Readings attempted to prove this theory and guess what the Royals together with the stars and celebrities present at glamorous Royal Wedding were whispering to each other on the big day.
Even though the Royal Nuptials between the Duke and Duchess of Sussex Harry and Meghan was a grand affair and was seen by many as a flawless occasion which went on without a trace of error, the internet was always going to find some hilarious sides to the occasion.
The YouTube page used the actual footage from the wedding day and added some bad lip reading and the result was hilariously amazing.
