Khaled and J Lo were shooting Thursday in Miami, where she was rocking a highly visible thong. Her pants for the video were hanging just low enough to put a virtual spotlight on her underwear.

We can guarantee this is no wardrobe malfunction. Everything is functioning just as planned. And damn well, too.

Yes, even in baggy pants ... Jenny's still got back and Khaled seemed to be getting one last look as they both left the set. Ya can't blame him. Stopping men in their tracks is kinda what J Lo does.
