TMZ caught sultry siren Christina Milian in L.A. doing something illegal --hint: a very Paris Hilton action! Also out in Tinseltown, a seemingly slender Lauren Conrad eating outdoors with a galpal, Hef's main girlfriend, Holly, showing off her cleavage free swag to the photogs, and David Spade, as usual, outside of Koi -- just shoot me!

In NYC: A radiant Julia Roberts leaving a hair salon in the meat packing district, and hooded duo Ashlee Simpson and Pete Wentz exiting the Ritz!
