Chris Rock broke a code of silence about President Obama's top secret birthday bash.
Rock dished on the star-studded celebration, which was closed to the press and not on the President's official schedule, during a surprise appearance at a Los Angeles comedy club. An audience member captured it all with a cell phone camera.
"As the party went on, it got blacker and blacker," said Rock.
The President turned the big 5-0 last August. The Obamas paid for the private party and tried to keep details under wraps.
The 200 VIP guest list included Tom Hanks, Whoopi Goldberg, Gayle King, and Jay-Z. No one has talked publicly about what happened - until now.
"It was the most unbelievable night of my life," Rock said.
Rock also said, at one point during the bash, he and Jay-Z joked around about why they weren't asked to perform.
Rock mentioned, "The President's never going to go, 'Yes, 'Big Pimpin'!' How'd you like that? Yes 'Big Pimpin' was amazing! Next year Jay's gonna do 'Money, Cash, Hoes.' No, it's never going to happen. Let's just be glad we're invited."
He even talked about first daughters Malia and Sasha doing a dance move called "The Dougie" to Beyonce's "Crazy In Love."
"They came from outta nowhere and Sasha and Malia started doing ‘The Dougie.' Think about this moment: a bunch of black people doing ‘The Dougie' in the house that slaves made."
Wednesday's New York Post calls Rock's stand-up a "Breach of informal code of silence."
