First Lady Michelle Obama returned to the Ellen show this week for a dance-off with host Ellen Degeneres. On set to promote the White House's #GimmeFive campaign, which asks participants to give five ways they are leading a healthy life, the FLOTUS also made time for a friendly dance break. Hitting the floor to the Mark Ronson and Bruno Mars smash "Uptown Funk", Obama and Degeneres serve up some choice moves with an awesome crew of dancers.
