First Lady Michelle Obama has a lot of things going for her. She's married to the president of the United States. She has two cute kids. Famously toned arms. A great wardrobe.

Oh, and she totally knows how to Dougie.

The first lady paid a surprise visit to ,America's futureTuesday afternoon. When she arrived, the students were already out on the field, prepping to perform a Beyoncé workout video as part of the first lady's nationwide "Let's Move" initiative.

Students were warming up to the Black Eyed Peas song "I Gotta Feeling" when Michelle Obama took the stage. As students began to recognize her, they screeched with excitement and rushed closer to the stage.

"Are you surprised?" Obama asked them.
We're guessing yes.

"I know all of you love Beyoncé, right?" Obama asked the kids. "Me too! Beyoncé is one of my favorite performers on the planet."

The first lady praised them for practicing the video, telling them it's great they're working out and having fun at the same time.

Then the kiddos displayed their new moves, although she'd warned them she hadn't had time to learn the moves in the song. "I'm gonna be off to the side trying not to embarrass myself," she said.

That didn't keep her from grooving on her own, though. Michelle Obama performed the Dougie, the Running Man and the Cha-Cha during the song.

But afterward, she returned to the stage, suggesting they do it again. This time, Obama got into it much more, picking up more of the moves. See, all she needed was a bit of a warm-up.

More than 600 schools performed the Beyoncé workout simultaneously this afternoon. Only one school, of course, was lucky enough to have the first lady doing the Dougie on the sidelines.
