Since giving birth to twins Finn and Hazel (not pictured) 17 months ago, Roberts has gone through a metamorphosis – from A-list movie star to practical mom. "To pull your focus away from your family life, it has to be great," the 37-year-old told Playbill of choosing a short Broadway run (Three Days of Rain) over a Hollywood film. Even while working, the twins are her priority. "If she has a two-hour break, she runs home," producer pal Marc Platt says. "She's utterly devoted to them."
