The two-term commander-in-chief also competed in a "Gangnam Style" dance-off with recording artist Usher at Monday night's invitation-only bash, which ran past 3 a.m. in the East Room and featured performances by Eric Benet, Janelle Monae, Swizz Beatz, Jennifer Hudson and Alicia Keys.
All social media was banned from the party, the newspaper said.
"The president and Usher had a dance-off to 'Gangnam Style' along with Janelle Monae. The president was a good dancer, but Usher threw down some amazing Michael Jackson-style moves," the Post quoted an unidentified guest as saying. "They played 'Single Ladies,' and all the women were dancing, led by [first lady] Michelle. Later, everyone lined up and did the electric slide, and the president led a party line around the room. Most people did the conga with him. The only people who weren't dancing were Bill Clinton [without Hillary], Timothy Geithner and John Kerry.
"Pick any party you've ever been to; this was 1,000 times better," the source said.
