After the surprise appearance, Obama, who is currently touring the U.S. to promote her biography Becoming, joined Santa to read the holiday classic The Night Before Christmas. 

The pair then joined forces for a dance.

After being coached on how to do the viral “Orange Juice” dance from Fortnite video game, Obama picked up the steps quickly while St. Nick struggled to keep up.
