Nicole Richie and Ashlee Simpson saw each other while indulging in a little shoe shopping at Barneys yesterday afternoon before Nicole headed off on her own to house hunt while Joel is on tour. The new mom and mom-to-be have more in common than ever these days and went on a double date with their rocker boys back in April when Ashlee's baby bump was still a question mark. Now she's so big and can get even more mommy advice from her starlet friend.
