Actress Katharine McPhee took everyone by surprise with a "Throwback Thursday" photo of herself and a very young Meghan Markle. She posted the pic to social media with the caption: "Meghan and I did musicals together as kids. She grew up to be the Duchess of Sussex and I grew up to star on the West End, so same life if you ask me." McPhee is currently in "Waitress the Musical" in London's West End.
