First Lady Michelle Obama is so serious about her Let's Move campaign that she joined in dancing with students Alice Deal Middle School in Washington, D.C. Tuesday. The video features a specially recorded version of Beyoncé's "Move Your Body."
"Beyoncé is one of my favorite performers on the planet," the first lady said. "And when she agreed to remake her video and do this 'Let's Move' flash workout, I was so excited, because this is what we’ve been talking about -- that exercise and moving can be fun."
