Jennifer Lopez joined fellow judges Randy Jackson and Steven Tyler on ‘American Idol’s’ Top 13 live performance show yesterday evening.

J’adore her Barbara Bui jumpsuit with a silver metal neckline.

As you know I love me some classic J-Lo and it doesn’t get more classic than a white-hot jersey jumpsuit.

She could have opted for better shoes; the black suede pumps are a total buzz kill.

Super-straight locks, H. Stern jewels and a dewy glow completed her look.
