On Tuesday night's episode of "The Tonight Show," the host answered that question with a resounding yes — at least until it was time to channel his inner OK Go on a treadmill.
Of course, it's no surprise that J.Lo, who kicked off her career as a dancer and still dominates the stage regularly, had no problem navigating the decades-spanning choreography, from MC Hammer's "U Can't Touch This" side-shuffle to Beyoncé's "Single Ladies" groove — and even her very own "Waiting for Tonight" wind machine routine.
Fallon hit every step right alongside her, but he needed a bit of a breather (at least for comedic effect) during their aerobic "Here It Goes Again" sprint.
However, it wasn't long before he came in like a "Wrecking Ball" with Lopez again.
The four-minute dance medley proved equal parts impressive and hilarious, and it also proved that these two really know how to take a twirl together. But that's something long-time "Tonight Show" viewers already knew.
Back in 2017, the duo faced off for a rapid-fire competition called Dance Battle. After improvising moves to made-up dances — like the Washing Machine Spin Cycle and the Hot Cowboy — Lopez was dubbed the champion.
But if you ask us, both then and now, the real winners are those of us who get to watch them.
