Crystal Kung Minkoff might never have appeared on TV before joining the cast of 'RHOBH,' but, halfway through the season, she's established herself as a bonafide star. And she joins Christian this week to talk about how it all happened, revealing who convinced her to hop on board. Plus, Crystal tells us her status with Erika, and Christian tries to make sense of the Tom car crash story using — what else? — Google maps.
