Jennifer Lopez makes no secret of the fact she works hard to keep her body in shape and judging by the bikini body selfie she posted on her Instagram stories her efforts are paying off.

The photo - which was taken while she was filming the stripper movie Hustlers - shows Jennifer wearing a bikini, sunglasses, and sporting a belly button ring
