(CNN) - First lady Michelle Obama has some moves–and so does Jimmy Fallon.
The pair teamed up for a video on the "Evolution Of Mom Dancing," which was released online Friday before the first lady's appearance on NBC's "Late Night with Jimmy Fallon."
Fallon and Obama appeared to be gearing up for some sort of showdown earlier in the day on Twitter–perhaps a repeat of their matchup from last year.
In February 2012, Obama invited Fallon to the White House for a calisthenics challenge, where the two competed in basic exercises as a way to promote her "Let's Move" campaign against childhood obesity.
And Friday night's appearance was shaping up to be Round Two.
