Kelly McKee Zajfen can't help but gush over longtime bestie Meghan Markle. "She's my best friend and such a support," Kelly told Us Weekly exclusively at the Alliance for Children's Rights 34th Annual Champions for Children on Thursday, March 19, in Beverly Hills. "It's incredible to watch her as a parent." Kelly added, "She leads also by example, and she's such a warm light, and she always says yes, so it means everything." Meghan, 44, attended the event on Thursday in support of Kelly, who is gearing up to welcome her third child with husband Julian Zajfen.
