Beyonce has released a new video for her song "Move Your Body" ... a catchy track in support of Michelle Obama's Let's Move campaign to fight childhood obesity.

Although the track sounds new, it's actually a re-do of her hit song "Get Me Bodied." Love the white knee high socks, B!

Jay-Z's wifey is busting a move with children in the middle of the school cafeteria. Beyonce's moves are definitely motivating us to get up and dance!
