Jennifer Lopez recruited 'American Idol' alums Pia Toscano and Jessica Sanchez, among others, to sit on a stoop and sing with her on a stage recreation of the Bronx before she performed her new song 'I Luh Ya Papi' on 'Idol' last night (March 20).

It was a full on production, with Jenny From the Block back in action, surrounded by graffiti and more. Kudos to the set designers; they really transported us to an urban landscape, with J. Lo as our tour guide.

She sparkled and played off her backup singers and French Montana, too.
