Michelle Obama jumped right into the holiday spirit with an epic dance-off with Santa Claus.
The former first lady, known for her dance moves, made a surprise appearance Thursday at a children’s hospital in Denver, Colorado.
When asked by a child at Children’s Hospital Colorado to name her favorite dance move, Obama replied, "I don’t think any of my favorite dance moves have names to them. I just move to the music. I just like to move."
A child in the audience then showed her how to do the “Orange Justice” dance from the popular Fortnite video game.
Obama, 54, not only got up and danced, she also got Santa to dance and encouraged everyone in the audience to dance too.
