Barack Obama said his wife Michelle made him "a better man and better President" before they danced at the Commander in Chief's Inauguration Ball.
The Obamas were both seen singing the words to Al Green's song Let's Stay Together, which was performed by former American Idol contestant Jennifer Hudson.
Michelle Obama was wearing a long red dress which was reportedly designed by Jason Wu and will go to the national archives.
Beyonce "lip-synched" the national anthem at President Obama's inauguration because she did not have time to rehearse with the band.
A day of grand political theatre lies ahead, but President Obama knows his history and will be steeling himself for a turbulent second term.
Presidential inaugurations are normally highly scripted events, but things don't always go according to plan.
