The romance between Nicole Richie and boyfriend Joel Madden is getting stronger than ever as they reportedly have exchanged rings.
The tiny socialite was spotted wearing ring on her wedding finger. Though so, friends of the couple denied they've been engaged, saying "They are not engaged but they did exchange rings. It wouldn't be surprising if they are engaged in six months."
Richie once engaged to longtime boyfriend DJ AM, while Madden ended his two and half years relationship with pop singer Hilary Duff November last year.
