"She will be a part of me until the day that I check out," Joely, 53, tells Closer. "Weirdly, we're still in it together."

Joely has helped Natasha's widower, Liam Neeson, raise the couple's two sons, Michael Neeson, 22, and Daniel Neeson, 21. "The years were very, very difficult when she left us," says Joely. "But we've all looked after each other and stepped up to the plate. No one could fill her shoes, of course, but we're trying to be the best people we can." Joey confides to Closer, "I believe all our loved ones are around us."
