Nicole Richie NRICHIE040307_01.jpgSay what you will about Nicole Richie and Joel Madden, but they're certainly not ones to be dragged down by history! We spotted the couple at Mr. Chow's last night despite only a few weeks having passed since Joel's now-infamous paparazzi-shoving incident. This time around, however, the pair appeared positively peppy (Nicole even cracked a smile!) on their way out of the restaurant before heading home. (Not that they stuck around to chit-chat, mind you - this is Nicole and Joel we're talking about, not Mary Carey!)
