Sorry, it's not the video for "Run the World (Girls)," but Beyonce did release a different music video today in support of Michelle Obama's "Let's Move" campaign to fight obesity.

The song, "Move Your Body," is a retooled version of B's hit "Get Me Bodied" -- and the new video shows the singer break it down in a middle school cafeteria while wearing short shorts and knee socks.

The video will be distributed to junior high schools across the country to, as Knowles puts it, promote the benefits of healthy eating and exercise."

In an earlier, behind-the-scenes video Beyonce also said "What we want to do is make it fun by doing something that we all love to do, and that's dance."

Shools across the country will reportedly perform the dance moves during a broadcast on Tuesday, May 3 at 1:42PM EST.
