Prior to stopping traffic with the signs on her skirt, Lindsay Lohan spent yesterday afternoon shopping for jewelry at XIV Karat in LA. At the Paper magazine luncheon Lindsay talked to ET about how "everybody should be who they are" and her plans to travel to Sierra Leone with malaria vaccinations, but before that there are parties to throw — of course. LL has stepped in to host next week's Scandinavian Mansion gala where Britney was originally scheduled to appear. Well, Linds has gotta pay the rent somehow, especially now that according to InTouch her roommate Courtenay Semmel is out because the starlet is way too messy. What better way than a party paycheck while she waits for those roles and album sale checks to start rolling in.
