Watch : Nicole Richie Seemingly Reacts to Hilary Duff’s New Song Amid Joel Madden RumorsHarboring hard feelings about her exes is so yesterday for Hilary Duff. Still, remaining friends 20 years after a romantic relationship ended isn't for everybody, but it has worked out for her and Joel Madden. "I brought two of my dearest friends to New York City tonight," she told the crowd in announcing the Good Charlotte rockers. In fact, they go all the way back to the '00s, the now-38-year-old Lizzie Maguire alum having dated Madden when she was a teenager. But even though their young love fizzled in 2006—and Madden coupled up with his eventual wife Nicole Richie that same year—Duff insisted at the time there was no big drama behind the scenes.
