Jennifer Lopez was out on the balcony of a Miami hotel yesterday to take a snack break during a photo shoot. Today she spent her afternoon playing at the pool with her kids. She's in Florida after a whirlwind week of travels that brought her to LA for Larry King's Haiti telethon and NYC to celebrate her friend Scott Barnes's new book of makeup tips. She opened up at his party about her twins Max and Emme playing with her lipsticks, saying, "Oh, my God, does she play with the makeup . . . Both of them do. Max too. They like to paint themselves and you." The frequent flying will continue for J Lo if she decides to join her colleagues in the music industry at next weekend's Grammy Awards.
