Jennifer Lopez had hoped to give birth to her twins on St. Valentine's Day (14Feb08), according to her gift registry details. The singer/actress gave birth to a boy and girl on Friday (22Feb08) - but Internet blogger Marc Malkin has uncovered information suggesting the babies were a week late. Lopez and her husband Marc Anthony are registered at celebrity baby boutique Petit Tresor as Miss Valentine and Mr. Valentine, with a due date of 14 February, 2008. Among the items on the list are baby booties, BabyBjorn carriers, matching blue and pink Baby CZ cashmere sets, mink hats and a men's Petunia Pickle Bottom diaper bag. The New York Daily News has reported Lopez hired Petit Tresor to design baby nurseries for her three family homes in Bel Air, Long Island and Florida's Fisher Island.
