During an appearance on Watch What Happens Live this week, Hilary Duff opened up about how she felt when Aaron Carter tweeted that he loved her. Hilary said, “It was so many years ago. I literally haven’t see him in . . . So it’s uncomfortable.” When the show’s other guest, Giada De Laurentiis, asked if Hilary had dated Aaron, Hilary explained, “Yes, I did. When I was 13. He was very sweet . . . when I was 13.”
