Hollywood celebrities and DC politicos are rubbing shoulders and having a few laughs tonight at the annual White House Correspondents Dinner.

Joel McHale, the star of NBC's "Community" and E!'s "The Soup," is hosting this year's event.

The guest list this year includes Tony Goldwyn who plays the President on ABC's "Scandal," Oscar winner Lupita Nyong'o, "Live! With Kelly and Michael" co-hosts Kelly Ripa and Michael Strahan.

All eyes will be on President Barack Obama and who he pokes fun at when he takes the microphone.
