NY Post:

NICOLE Richie isn't taking Benji Madden and Paris Hilton's split very well. Sources tell Page Six that since Madden split from Hilton, Richie's best pal, Nicole "has been really possessive and stops him from talking to other girls." Richie, who has a baby with Benji's twin, Joel Madden, was spotted at a party for the Maddens' band, Good Charlotte, and their latest album, "Greatest Remixes." Our spy said, "Benji was approached by dozens of ladies. Girls were trying to flirt with him . . . but Nicole kept getting in the way." The source noted that Richie "stopped every girl trying to take a photo of him," and even "dragged him by the arm" away from a busty blonde.
