Jennifer Lopez showed off her curves in a little white dress on the set of The Back-Up Plan in NYC yesterday. Her workdays have been sweetened with visits from her family, but today it was Jennifer's turn to play support system. She and Marc headed to a Miami Dolphins press conference, where it was announced that Marc will be a partial owner of the football team. Jennifer may not be a huge sports fan, but she's got a brand new jersey ready to go for when she's around to watch from the stands.
