Jennifer Lopez, arrives at American Idol in a rounded posterior & skin-tight LBD

          

 And Jennifer Lopez continued to make the most of her impressively-toned assets as she was pictured arriving at the American Idol studios in Hollywood, California, on Thursday evening, dressed in a black mini dress.
The Shades of Blue actress was a sight to behold as she squeezed her rounded behind into the form-fitting garment which skimmed her thighs, exposing almost the full length of her shapely legs.
