Nicole Richie is with Joel Madden as the most important person in the life of Good Charlotte.

Sources close to Richie say she is “moving stuff out of her West Hollywood condo into his Glendale home,” and Joel’s bandmate, brother, and next-door neighbor Benji is “furious.” The source also said Joel and Nicole “have already become inseparable, and spend almost every night together.” Richie is expected to join Madden when he deejays on New Year’s Eve at the Palms Hotel in Vegas far from Madden’s ex, Hilary Duff, who will celebrate ‘07 at the DKNY Jeans Bash at the Setai in Miami.

At least shes moved on from DJ AM, since he only wanted was her fame. Maybe he should of stayed fat and had somemore cupcakes. My treat.
