Showing off her curvaceous figure, the “Wedding Planner” actress strolled along in tight black workout pants with a white t-shirt and charcoal zip-up jacket.

Aside from her movie duties, Lopez has also been spending time kick-starting her new charitable endeavor, the Maribel Foundation.

Inspired after she and hubby Marc Anthony found a lump on the head of daughter Emme, Lopez tells, “We both got very nervous, and I just remember my heart sinking to my feet.”

The Maribel Foundation helps provide pediatric medical services for those who cannot afford to pay themselves.
