Nicole Dumps DJ for Dillon?

Is Nicole Richie trying to outdo her ex, DJ AM? We told you last week it looked like AM had moved on already and was reportedly chatting up a fashion designer, now US Weekly is claiming that Nic is getting up close and personal with actor, Matt Dillon (former ex, of Cameron Diaz). A source with the mag reports that the twosome, "'cuddled and looked very cozy' at the Chateau Marmont after they hooked up at a Dolce & Gabbana party at the Hollywood Roosevelt Hotel last week." Needless to say, Nic's peeps aren't commenting, and his peeps say no way. With all the recent pics that keep popping up of Nicole and DJ AM, we say this is one couple that will more than likely be on again before the summer's over.
