Just like Nicole Richie and Christina Aguilera, Jennifer Lopez called upon the experts at Hollywood favorite baby boutique Petit Tresor. The new mom opened a lengthy registry and had owners Nina and Sam help her design fabulous nurseries for the arrival of her twins! So what’s in store for the twins? J.Lo will keep her new baby boy wrapped in a cashmere cardigan, hat and bootie pants from Baby Cz, $279 and, of course, a matching pink set, $279, for the new fashionista of the family. The twins will also have a set of Plain Mary’s Hunk and Babe onesies, $169. For the nursery, the twins will dream away in Chelsea Sleigh cribs, $1390 each while Mom and Dad relax in Glam Gliders $1,420 each. And when they need changing, the twins will have a Clara changing table, $1780. And why give up gorgeous handbags just because diapers are involved?
