Jennifer Lopez's romantic timeline.
Jennifer Lopez pushed the limits of how short a dress can actually go at Thursday night’s taping of American Idol, where she donned a ridiculously short, black minidress that left very little for the imagination.

The backless dress nonetheless showed off J-Lo’s body — not to mention her toned legs. Remind us: How is she 42 years old, again?

To complete last night’s look, Lopez wore her hair in a flirty updo, and matched her sequined dress with a bair of Christian Louboutin stilettos.

Overall, it was another fashion risk for J-Lo, and a step forward from her all-metallic look on Wednesday, which received some mixed reviews from our Celebuzz readers.
