Nine-year-old Big Three, meet teenage Big Three.  This Is Us stars Mandy Moore and Milo Ventimiglia took to Twitter on Friday to share a family photo unlike any other. This Pearson family snap, taken on the show's set, features the actors that play Kate, Kevin, and Randall when they're children and when they're teenagers. Thanks to the out-of-order chronology of the show, the eight actors never share screen time together, making the snap all the more special.
