Courtney Cox, David Arquette and Laura Dern had a nice little outing on Rodeo Drive in Beverly Hills yesterday.  The trio shopped at Cartier, Chanel and some other boutiques for good measure. (BTW niiiice look David Arquette, are you channeling your inner Pete Doherty??) Maybe they can give Vanessa Manillo some tips on how to shop "like a rich person".
