The first-lady of United States-Michelle Obama was at it again with Ellen DeGeneres—and this time, they were not battling by doing press ups, a challenge Michelle Obama comfortably won the last time.

Instead, the two women danced to “Uptown Funk” on Ellen’s show. The first lady was so enthusiastic, her microphone fell off, and the group had to start the dance over—all in promotion of Michelle Obama’s fifth anniversary of her health and fitness campaign called “Let’s Move!”

The dance was beautiful but even before they started it, the words they exchanged were hilarious—you know Ellen knows what to say and what time to get you laughing. But Obama is another one—she said, Ellen is from the street…LOL

On the show, Michelle Obama announced that at this year’s White House Egg Roll, the So You Think You Can Dance all-stars will teach a dance to “Uptown Funk.”

Now, watch Ellen and Michelle do the dance…
