Jennifer Lopez was getting into character on set of her new TV show 'Shades of Blue'. The super star was spotted showing off her serious acting chops filming late night scenes on the streets of Brooklyn. Brandishing a gun at a pair of armed robbers who had taken a hostage after holding up a Bodega. The American Idol judge was dressed in character as single mother, Detective Harlee Santos wearing skinny jeans, a cream shirt and a trench coat. She was also sporting her new short ombré bob. A far cry from her usual super glam look. In the scene Jennifer shoots one of the men before rushing over to help the victim who was held hostage. NBC's Shades Of Blue, which is set to air mid season, also features Ray Liotta, and Waren Kole.
