Nicole Richie has got engaged to Hilary Duff's ex Joel Madden. According to Life and Style Weekly, Joel popped the question to Nicole and the couple were spotted visiting a jewellery store in Los Angeles. The Simple Life star and the Good Charlotte singer reportedly looked at engagement rings. An employee at the swanky boutique revealed, "Of course he would never get her a half-price ring. You can tell they're crazy about each other. His arm was around her the entire time." Richie, 25, started dating Madden, 28, in late 2006 after he broke up with Hilary Duff. |
