Jennifer Lopez was spotted at a gym in Philadelphia over the weekend....she was here with her fiance Alex Rodriguez, who is on the ESPN broadcasting team and was here for the Phillies game last night. She's staying in great shape as she films a new movie called "Hustlers". In the film she's plays a stripper, and so duty calls for her to look great. And she sure does! Check out this pic of her she posted on Instagram, J Lo and her bikini darn near broke the Internet!
