I’m sure you’ve seen this by now, but Jennifer Lopez gave a bit of a dancing masterclass on Jimmy Fallon’s talk show this week, as the pair of them demonstrated the evolution of dance in music videos.

I particularly like the bit for Waterfalls, which I didn’t know what an iconic dance but must be, the Wrecking Ball space hoppers, and the Bad Guy hoodies.

What I most enjoyed though is how wrecked Jimmy Fallon was by the end, when it looked like J-Lo barely broke a sweat. She rules.
