It's not every day the First Lady of the United States is seen dancing to the beats of a top chanteusse.
But after standing on the sidelines watching students perform a dance routine to Move Your Body, Michelle Obama could not resist joining in.
After her initial reluctance - due to not wanting to "embarrass" herself - the 47-year-old showed the children from Alice Deal Middle School in Washington how it's done.
"It's about dancing, it's about moving," she said afterwards.
Her dance moves were for the video entitled Let's Move Flash Workout, part of her campaign which aims to get children moving to try to curb childhood obesity.
With one-third of the nation’s children estimated to be overweight, the mum-of-two's goal is to contribute towards solving the problem.
