Jennifer Lopez and Casper Smart worked on their American Idol performance for four hours, and last night viewers got to see what all of their rehearsals were for. Jennifer sang her sexy song “Dance Again”. She was accompanied by male backup dancers, but since Casper likely choreographed this performance, Jen and Casper only performed with each other towards the middle of the performance, and it was pretty hot. They’re muy caliente for each other and Jen says “He’s so cute!” after she’s done. I still don’t see that, but at least Casper treats his sugamama “like a queen”.
