Jennifer Lopez channeled Britney Spears in a sparkly nude bodysuit while performing in Panama yesterday. She tweeted at her fans after wrapping things up, "Gracias Panama! Thank you Panama! Great show tonight! Love!" The show kicked off her Dance Again World Tour, which she's been prepping for over the last few months. J Lo will hit the stage solo in South America until July 14, when she'll join up with Enrique Iglesias to continue appearances in Canada and the US through August. Until then, J Lo has another man nearby, her boyfriend Casper Smart, who is one of the choreographers for the tour.
