Sean Penn, Scarlett Johansson, Chris Colfer & More Celebs Attend Washington Correspondants Dinner [PHOTOS]

While Hollywood was out in full force last night (April 30) for the 2011 White House Correspondents’ Association Dinner at the Washington Hilton on April 30, 2011 in Washington, DC, all eyes were on President Barack Obama.

President Barack Obama poked fun at everyone, from his wife to Donald Trump, during the annual White House Correspondents dinner, before ending his speech with a tribute to journalists who brave deadly conditions to get a story. Here are a few of Barack’s zingers:

“Donald Trump is here tonight,” said Mr Obama, beaming. “Now, I know that he’s taken some flak lately, but no one is prouder to put this birth certificate to rest than The Donald. Now he can get to focusing on the issues that matter. Like, did we fake the moon landing? What really happened at Roswell? And where are Biggie and Tupac?”

The president was followed on stage by Seth Meyers, the head writer and “Weekend Update” anchor for “Saturday Night Live.” Meyers poked fun at news outlets such as C-SPAN, MSNBC, Fox News, CNN and The New York Times. He also focused on the 2012 Republican presidential field — a roster he said “sounds like season 13 of ‘Dancing With the Stars,’ and not the stars (but) the dancers.”

The big Hollywood news of the night was that Scarlett Johansson and Sean Penn were photographed holding hands. I can only wonder what Ryan Reynolds thinks about all of this.
