Hollywood A-listers including Charlize Theron, Lindsay Lohan, George Clooney, Kate Hudson and Reese Witherspoon descended on Washington, D.C. to turn the annual meal into a star-studded event.

Kardashian, who brought along her mother Kris Jenner as her date, helped her 14.5 million followers on Twitter.com get in on the action by posting messages and photos from inside the bash.

She shared a photo of the President and First Lady Michelle, and took it in her stride when emcee Jimmy Kimmel poked fun at her by telling Obama and the audience, ""If you're looking for the biggest threat to America right now... She's right there. Her name is Kim Kardashian.""

Kardashian tweeted, ""Pretty funny speech I must admit.""

The brunette beauty also showed off snaps she took with actress Sofia Vergara and lifestyle guru Martha Stewart.
