'She's always been a princess. She's carried herself on that level from day one.'
Markle Jr is engaged himself, and says he is planning on inviting the prince to his wedding.
The Suits star, 36, told Vanity Fair earlier this year that her relationship with Harry was 'a great love story'.
The couple have reportedly been dating since early last year, but it wasn’t until last November that Kensington Palace confirmed the pairing with a statement, saying the prince was worried for her safety.
Soon after, Harry and Meghan, who is four years his senior, were spotted together attending one of the Prince's polo matches in England.
