Transcript for Meghan Markle's mom lands in London
I don't recommend it. Our "Gma" cover story, nine days until the royal wedding. Where is that clock? Oh, we don't have the clock. George's clock, he was begging for it. Wow. We're seeing Meghan Markle's mom. There it is. Yeah. It's not nine day, it's eight days, 22 hour, 45 minutes and let's say hello. Take it away. Eloping -- no, kidding. We often hear Meghan gushing about her mom. It turns out she will be meeting the royal family in person. Not only is her mother meeting the Royals she's also helping with last-minute plans and is preparing to make history on the big day. With less than ten days to go before Meghan officially becomes a princess, "Good morning America" has learned that her mom, Doria radlan, has landed in London with the last-minute wedding prep. She will meet Harry and Meghan's nearest and dearest including Jessica Mulroney. It's no doubt a stressful and busy time for Meghan and so having her mother by her side especially on mother's day will no doubt alleviate some of those nerves. Reporter: The 61-year-old African-American social worker and yoga instructor will meet Harry's relatives for the first time including the queen, prince Charles, prince Williams and princess Kate. The meeting also highlights the historic significance of Meghan becoming the first biracial woman to marry into the British royal family. Like Meghan, Doria will need to learn to curtsy and master the royal traditions of everything from taking tea to table manners and etiquette. This trip sees Doria thrust into the middle of the royal circle and she's staying at kensington palace with Harry and Meghan and so she has them to help guide her along the way, teach her protocol and perfect her curtsy. Reporter: After her parents divorced when Meghan was 6 her mother exposed her to the soup kitchens of L.A. And the impoverished areas of Jamaica instilling in her the values she has today. Meghan said both my parents came from little so they made a choice to give a lot and Harry flew her over for the invictus games and has said how much he adores her. Reporter: What about Meghan's dad. He was en route from Mexico on his way to London and next week he'll join Doria and Harry and Meghan at a private wedding rehearsal at Windsor castle where it'll be the parents' first chance to see how big this fairy tale wedding is. Reporter: Kellogg announced Meghan's parents will make history when Doria accompanies Meghan to St. George's chapel, the first mother to take on that role and her father will then walk Meghan down the aisle. So, a lot of first for both families. Big week but another first now that she's in London Meghan's mom will get to see her finished dress for the first time. It will be an exciting moment.
