Paris and Nicole: That's My Bag, Baby!

TMZ's G-Hollywood spotted Nicole Richie, Paris and sister Nicky as they left Maxfield on Melrose on Monday night. The reunited BFF's shopped 'til they dropped, then left the swanky strip with their assistants carrying their bags -- and set the paparazzi into a holiday frenzy.

Also out on the town: Justin Timberlake, platinum-selling rapper Xzibit, Bobby Brown, Ice T aka Iceberg along with wife Coco, and redheaded party girl Lindsay Lohan -- who was "too tired" to sign an autograph. Come on Lindsay!
