Markle, 36, can clearly be seen mouthing something in a video taken during the moment in question, which has gossipers gossiping.
"While the audio wasn't clear, it definitely seemed like she let out an 'Oh f**k' as they crossed through the gates of Windsor Castle," writes Courteney Larocca for HollywoodLife.
"Sure, some people think she just said 'oh wow', but we're really hoping it's the first one."
Others took to Twitter with excited reactions to the newest member of the Royal Family's perceived profanity.
According to the Daily Mail, Prince Harry turned to Meghan at one point during the 25-minute ride and said, "I'm ready for a drink now".
