Our First Lady was back at it again yesterday: dancing up a storm in the name of a good cause at the White House South Lawn.

This time, the dancing took place to kick off a new program offering physical fitness incentives to military families — and she chose Willow Smith's "Whip My Hair" and Beyoncé's "Crazy In Love" to make moves to. For the record, we will never get tired of this.
