I bet you cant see me behind these cashmere tunics!

What could be so important as to prompt Nicole Richie to sit between the racks of clothes at Marc Jacobs to make a phonecall? Possibilities:

-Calling Paris to be all like "You will not believe what Britney said about you" so that all can get back to normal in this world
-Calling Marc Jacobs himself to see if he can reduce the size 0 to a size -2 or -4 at least
-Calling Lindsay who she now sponsers in AA to remind her that Rum is NOT a food group
-Calling Rachel Zoe to leave fart noises on her voicemail
