Jennifer Lopez and Cameron Diaz
Jennifer Lopez dazzled on the red carpet before the Academy Awards in a sparkling Zuhair Murad gown.But when the American Idol judge took the stage with Cameron Diaz to present the Oscars for Best Costume Design and Makeup, her look – and that dangerously plunging neckline – wasn't so best-dressed-list worthy.
Lopez seemed to have a slight wardrobe malfunction when her dress shifted on top, but it was a close call.
