Hilary Duff tells Seventeen magazine she was shocked to see Joel Madden going out all the time after their split. “All of the going out he did after we broke up sort of shocked me,” the singer/actress confessed. “Like, that’s just so out of character for him, and when we were together, he hated stuff like that, so I felt like I didn’t really know him as well as I thought I did.” Despite things not working out with the Good Charlotte singer, Duff still hopes to settle down. “I still want the cookie-cutter American dream – to get married, have kids, and have a house with a picket fence,” she said. “I still believe that marriage can work.”
