Jennifer Lopez knows how to flaunt it. On Wednesday, the singer showed off her impeccable dance moves when she participated in a heated dance battle with Jimmy Fallon on The Tonight Show. While the host certainly made us laugh with his "Walking on a Moving Bus" move, nothing can quite compare to J Lo's "Hot Cowboy." Seriously, you might need a tall glass of water to cool down after this one. Although, we'll always be partial to their signature "Tight Pants" duet.
