VIDEO : Milo Ventimiglia And Mandy Moore Have A 'This Is Us' Tradition

39-year-old actor Milo Ventimiglia recently opened up to ET's Lauren Zima at the FYC screening and panel for 'This Is Us' on Wednesday in Los Angeles, California. The actor revealed that he and co-star Mandy Moore have established a ritual surrounding the show. "So, Mandy and I have this tradition now where we sit and watch the episodes together, which is kinda funny." Says Ventimiglia. "There [are] so many moments [where] we were literally just looking at each other and we're both crying -- or she's crying and I'm, like, supportive or vice versa."
