The former Suits star attended last year's games in Toronto with Harry, and joined in again this year when she sheered on United Kingdom athletes at the trials.
Lip readers reckon they know what Harry was saying to his new wife.
Later they joined the Queen, the Duke and Duchess of Cornwall, the Duke and Duchess of Cambridge and other family members on the balcony of Buckingham Palace to watch the spectacular display in the skies above.
Regardless of how her dress was received, the event was a historic moment for Meghan, as it was the first time she appeared on the balcony of Buckingham Palace with her new family.
"I don't envy Meghan Markle's life, because it seems like she's now trapped in a bubble with sooooo many rules and regulations on etiquette". Then she dips into a curtsy, smiling the whole time.
We wouldn't be surprised if that's really what he said.
Meghan Markle and Kate Middleton wowed the crowds at today's Trooping the Colour with a pair of stunning outfits. Some seconds later, Harry then said, "Now", allowing Meghan to curtsey in flawless time, along with the rest of the royals. The couple first discussed an unknown subject, with Harry telling Meghan, "Errr". He even explained what was going to happen next before each ritual.
Prince Harry was reportedly calming Meghan's nervous throughout the whole parade. It's reported that the couple have lots of work engagements planned until the new year.
