Is designer Marc Jacobs looking for a little publicity bump from MTV? "Marc hired Lauren Conrad to do his [New York Fashion Week] show," an insider tells Page Six. So what's the big deal, you ask? Well, the real models are in a tizzy because they have to sign releases for The Hills in order to walk in Marc's show. "They are very put out that Marc succumbed to putting on one of 'those shows' -- you know, the publicity shows," the spy says. Looks like everyone's using LC to get famous these days!
