Red-Carpet Recap: "The Back-up Plan" Premiere
Jennifer Lopez has been hot to trot lately, and last night's premiere of "The Back-up Plan" was no exception.
The actress (who wore a sexy metallic Gianfranco Ferré dress) was joined by Heidi Klum, who rocked a modified version of Emilio Sosa's "Project Runway" Episode 11 winning dress.
