Jennifer Aniston on set in Pennsylvania!

Romance can do wonders for one’s attitude and appearance and it looks to have quite the positive effect on Jen Aniston. The formerly single actress looked stunning and happy on the Pennsylvania set of “Marley and Me” Monday morning, despite being dressed very casually and covered up in a big jacket to protect her from the rainy weather. Aniston was glowing and smiled cheerfully, perhaps with memories of John Mayer and his “wonderland” of a body bouncing around her mind.
