I guess the truth is he thought Hilary was fat

Joel Madden has jumped back into the dating game after his split with Hilary Duff - he is reportedly romancing Nicole Richie. Madden and Richie were spotted out at Hollywood hot spot Teddy's at the Roosevelt Hotel on December 2nd, less than a week after Madden confirmed the split from Duff. According to Us Weekly, Richie, 25, and Madden, 27, were spotted holding hands and dancing, with one clubgoer adding, "Nicole couldn't stop smiling. I've never seen her happier." The following night, the new couple hit the town again, joining Madden's twin brother Benji and his Australian girlfriend Sophie Monk for an intimate dinner at the Polo Lounge in Beverly Hills. Madden, 27, and Duff, 19, announced they had split late last month and blamed the break-up on their age difference.

Um.. the only way I can explain this is that Joel confused Nicole for a guitar string, and thought that he was focusing on his music.
