Thomas Markle will take his place beside Harry's bride-to-be before the wedding ceremony begins, according to Meghan's half-sister Samantha.
"Ms. Markle is grateful to everyone who has followed her social media accounts over the years", a royal source told ABC News.
The queen would also have loved the family to see what had been done at Frogmore: the house has just been renovated by a group of friends as a 70th wedding anniversary gift to her and Philip.
Her comments were aired after the U.S. actress wowed Brixton when Harry brought his bride-to-be to the heart of London's Caribbean community for their first official visit in the capital. Instead, updates about their lives and careers are posted on one set of accounts, run by Kensington Palace.
It was Harry and Meghan's second public event together since the fifth-in-line to the throne and the American actress announced their engagement in November. Kate Middleton, Prince Harry, and Prince William, for example, don't have personal social media handles.
Markle, a Los Angeles native, also intends to become a United Kingdom citizen, a process which will take several years. And also keep in mind that I've been working on my show [Suits] for seven years.
The couple will marry at Windsor castle on May 19. I think they're [a] very good match, I'm very happy for them, Meghan and Harry.
